In the “success count”, information indicating the number of times the key corresponding to the note has been pressed correctly by the performer is stored, and after the musical piece is played, the key corresponding to the note is accurately determined by the performer. When the button is pressed, the numerical value stored in “Success Count” is incremented by one. On the other hand, when the key corresponding to the note cannot be pressed, the numerical value stored in “Number of successes” does not change. The “recent value” is an area in which information indicating whether or not the key pressing operation has been correctly performed for each note (○, × in the figure) when this musical piece is played at the closest time is stored. . Accordingly, the information stored in the “recent value” is updated according to the performance content every time the music piece is played.
[0029]
The “key-on time” is an area for storing information for analyzing how accurately the timing at which the performer starts pressing the key is stored. Information of items such as “value” and “average value” is stored. "Recent" shows the percentage of the key corresponding to each note when the song was played at the closest time to the time when the actual pressing started with respect to the time when the key pressing should start Is stored. Accordingly, the information stored in the “recent value” is updated according to the performance content every time the music piece is played. “Average value” indicates an average value of the ratio of the time when the actual pressing is started to the time when the key pressing corresponding to each note is to be started for the key corresponding to each note when the music piece has been played in the past. Information is stored. Here, “average value” is not an average value for each note, but an average value for each phrase (for example, one phrase consisting of four sounds) obtained by dividing the music. Of course, the information stored in the “average value” is also updated when the average value fluctuates due to the performance of this music piece. Note that the “recent value” and “average value” in the above “key-on time” and “key time” described below include the actual performance time (in the case of the key-on time, from the previous key-on time) The time calculated until the key press start time) / regular time × 100, that is, a value indicating the percentage of the regular value as a percentage is stored.
[0030]
The “key time” is an area in which information for analyzing how accurately the time during which the performer is pressing the key is operated is stored. Information of items such as “value” and “average value” is stored. The “recent value” stores information indicating the ratio of the actual pressing time with respect to the exemplary pressing time for the key corresponding to each note when this musical piece is played at the closest time. Accordingly, the information stored in the “recent value” is updated according to the performance content every time the music piece is played. In the “average value”, information indicating the average value of the ratio of the actual pressing time to the pressing time as an example for the key corresponding to each note when this musical piece has been played in the past is stored for each phrase. The Of course, the information stored in the “average value” is also updated when the average value fluctuates due to the performance of this music piece.
[0031]
“Velocity” is an area in which information for analyzing how accurately the player presses the key press is stored, and “recent value” is stored for each note constituting the song. And information of items such as “average value” is stored. The “recent value” indicates the actual pressed strength with respect to the strength to be pressed (for example, the MIDI velocity value) for the key corresponding to each note when this musical piece is played at the closest time. Stores information indicating the ratio of. Accordingly, the information stored in the “recent value” is updated according to the performance content every time the music piece is played. The “average value” includes information indicating an average value of the ratio of the actually pressed strength with respect to the strength to be pressed as an example for the key corresponding to each note when the music piece has been played in the past. Stored for each phrase. Of course, the information stored in the “average value” is also updated when the average value fluctuates due to the performance of this music piece. The “recent value” and “average value” in “velocity” indicate the actual key pressing force (velocity value) ÷ normal velocity value × 100, that is, the percentage of the normal value as a percentage. Stored values are stored.
[0032]
The “first look master degree” is determined based on the information stored in the areas such as “miskey”, “key-on time”, “key time”, and “velocity” described above, that is, based on the analysis result of the performance contents of the performer. This is the area where the technical level of the performer is stored. Here, in this embodiment, three practice steps are prepared in order to practice the performance of one musical piece, and information for evaluating the technical level of the performer in three stages is stored for each step. Here, an area for storing the evaluation information of the technical level is prepared for each phrase (for example, one phrase / four sound configuration) obtained by dividing the musical piece, and the technical level of the performer is evaluated for each phrase of the musical piece. Can be stored.
[0033]
Here, FIG. 7 shows the contents of each practice step in the present embodiment, the contents of each step, and the contents of adjustment of the practice music (contents of component sound reduction) for each technical level in each step. As shown in the figure, step 1 is a step in which only the melody portion of this music is played. At level 1, short notes are deleted from notes constituting the melody portion, and a continuous tone is a single tone. Adjustment is made to reduce the number of constituent sounds. Here, the short sound deletion is to delete a relatively short sound in the entire music piece, and the continuous sound shorting is to change the continuous part of the same sound to an extension of a single sound. Next, at level 2, the short sound is not deleted, and only a continuous tone is made. In level 3, the performance of the original music (only the melody part) without the reduction of the constituent sounds is performed.
[0034]
Next, step 2 is a step of playing only the chord portion of the music piece. At level 1, adjustment such as making a single chord is performed, and the number of constituent sounds is reduced. Here, making a chord into a single tone means changing a chord composed of a plurality of tones to only a single tone of the root. Next, at level 2, adjustment such as simultaneous chording of distributed chords is performed, and the number of constituent sounds is reduced. Here, to make a distributed chord into the same chord is to change a distributed chord such as an arpeggio into a chord that simultaneously presses a key. At level 3, the performance of the original musical piece (only the chord portion) is performed without reducing the constituent sounds.
[0035]
Next, step 3 is a step of playing both the melody and chord of this song, that is, the entire song. At level 1, the melody part is subjected to the same constituent sound reduction as level 1 of step 1, and the chord is played. For the portion, the same constituent sound reduction as in level 1 of step 2 is performed. Next, at level 2, the melody portion is subjected to component sound reduction similar to step 2 level 2, and the chord portion is subjected to component sound reduction similar to step 2 level 2. In level 3, the constituent sounds are not reduced in both the melody part and the chord part, that is, the performance of the original music is practiced.
[0036]
Next, FIG. 8 is a diagram showing a data structure of the second profile area 123d. In the second profile area 123d, information indicating the teaching content and the response amount of the player, such as what kind of teaching is given to the player and how it is reflected in the performance operation content by the player. The player's profile information is stored. In the present embodiment, as a piece of information displayed on the display unit 124 and taught to the performer in order to teach a performance method, not a normal note but a deformed picture note is displayed. Specifically, when the musical score of the music is displayed on the display unit 124, for each musical note displayed on the musical score, a deformed musical note picture described in the column “Display picture” in FIG. 8 is displayed. Accordingly, in order to play the music, teaching information such as a key to be pressed, a timing to be pressed, a time to be pressed, and a strength to be pressed is notified to the performer.
[0037]
In the second profile area 123d, information on items such as “display count” and “response amount (average value)” is stored for each “display pattern” that is teaching information related to the performance method as described above. In addition, the “display pattern” obtained by transforming the musical notes as teaching information in the present embodiment is prepared with seven levels of patterns for each item such as “key-on time”, “key time”, “velocity”, and “key”. An area for storing items such as “number of times of display” and “response amount (average value)” is set for each of these pictures.
[0038]
Here, the “key-on time” is an information storage area about the timing of starting to press the key corresponding to the notes constituting the music piece, and the “display picture” of this item has a horizontal direction on the upper side of the notes as shown in the figure. Patterns with arrows are prepared. Here, the arrow to the left is a teaching content to the effect that the player should make the key pressing start timing corresponding to the note earlier. On the other hand, the arrow on the right side added to the note is a teaching content that the player should delay the timing to start pressing the key corresponding to the note, and the length of the arrow varies depending on each level. The level indicates the degree (for example, level 1 is the teaching information with the highest degree of teaching that the pressing timing should be advanced, that is, the teaching information that is urging the strongest attention). Note that a note without an arrow is a normal note, and it is not necessary to teach the player about the timing of starting to press the key corresponding to this note. Is the case.
[0039]
The “key time” is an information storage area about the time for which the key corresponding to the notes constituting the music is pressed, and the “display picture” of this item has a horizontal arrow below the note as shown in the figure. There is a picture with the added. Here, the arrow to the left is a teaching content to the effect that the player should shorten the key pressing time corresponding to this note. On the other hand, the arrow on the right side added to the note is a teaching content to the player that the key should be pressed for a longer time, and the length of the arrow that differs at each level. Indicates the degree of the teaching content. Note that a note without an arrow is a normal note, and this note is displayed when there is no need to specifically tell the player about the key press time corresponding to this note. It is.
[0040]
“Velocity” is an information storage area about the strength of pressing a key corresponding to a note constituting a musical piece, and the “display picture” of this item has an up and down arrow on the right side of the note as shown in the figure. Added pattern is prepared. Here, the upward arrow is a teaching content to the effect that the player should strongly press the key corresponding to this note. On the other hand, the downward arrow added to the note is a teaching content that the player should weaken the key press corresponding to this note, and the length of the arrow that differs at each level. Indicates the degree. In addition, a note without an arrow is a normal note, and it is not necessary to teach the player about the pressing strength of the key corresponding to this note. Is the case.
[0041]
The “key” is an information storage area as to whether or not the key corresponding to the note constituting the music is pressed, and the “display picture” of this item has a picture in which the display color of the note is changed. . The description in parentheses in the figure indicates the display color of the note. Here, the blue display color instructs the player to press the key corresponding to the lower pitch, and the red display color indicates the key corresponding to the higher pitch to the player. Is pressed, and the density of each color indicates the degree. Also, the notes displayed in black are normal notes, and these notes are displayed when there is almost no mistake in pressing the key corresponding to these notes and there is no need to teach them. It is. The "display picture" of this item, that is, the color change display, shows the pitch of the note at the position where it is placed on the staff, but in such a general display it may be wrong to press This is intended to alert a player who has a habit of depressing a key having a pitch lower than that note by displaying the note in blue.
[0042]
For each “display pattern” of each item as described above, the number of times of display so far is written as numerical information in the “display count” field. In addition, for each “display picture” of each item, the operation amount reflected in the performance of the player when the display picture is displayed, that is, the player's operation response quantity when each display picture is displayed and taught Is written as numerical information in the “response amount (average)” column. These “display count” and “response amount” are updated by an update process executed by the CPU 120 each time a performance is performed by the performer, which will be described later.
[0043]
Here, as the information obtained by quantifying the response amount, a tempo value, an actual time, or the like can be used in the case of “key-on time” or “key time”. In the case of “velocity”, the MIDI velocity value can be used, and in the case of “key”, the response amount can be quantified using the MIDI note number.
[0044]
Note that the display pattern of items such as “key-on time”, “key time”, “velocity”, and “key” may overlap for one display note. In this case, each item is displayed for the same note. A display pattern subjected to a corresponding modification is used. More specifically, when teaching to advance a “key-on time” and teaching to increase a “key time” for a certain note, an arrow to the left is added above the note. A note with an arrow pointing to the right side is displayed below the note.

B. Operation of the embodiment
In the PC 10 having the above-described configuration, the CPU 120 executes a performance teaching processing program group stored in the ROM 122 and the hard disk 123 based on the user's instruction input by the power-on and the operation unit 126 (not shown), and the like. Appropriate teaching contents corresponding to the performer regarding the performance method are displayed on the display unit 124 so that the performer can perform effective performance practice. Hereinafter, the operations of the piano 11 and the PC 10 will be described with reference to FIG. 9, focusing on the performance teaching process executed by the CPU 120 of the PC 10 when performing such performance practice.
[0046]
First, when a performer performs a performance practice using the PC 10 and the piano 11, the two are connected by a cable 12 as shown in FIG. Then, the PC 10 and the piano 11 are turned on, and the operation unit 126 is appropriately operated to instruct the CPU 120 to start executing the performance teaching process program group stored in the hard disk 123 in the PC 10.
[0047]
When there is an instruction from the performer in this way, the CPU 120 selects one of a number of practice songs stored in the practice song database 123 a of the hard disk 123 according to the performance processing program group stored in the hard disk 123. The practice song selection menu screen for making it appear is displayed on the display unit 124 (step Sa1). When the practice song selection menu screen is displayed in this way, the CPU 120 shifts to a standby state waiting for selection of a practice song from the performer, and determines whether or not the practice song has been selected by the performer (step Sa2).
[0048]
Here, when the player selects the practice music by appropriately operating the operation unit 126, an instruction based on the selected content is input to the CPU 120. When an instruction to select a practice song is input, the CPU 120 performs an adjustment process on the display contents to be displayed on the display unit 124 based on information such as what performance skill level the song has selected by the performer. (Step Sa3). Specifically, the CPU 120 reads out data related to the selected practice song (see FIG. 4) from the practice song database 123a of the hard disk 123, and the music selected by the performer stored in the first profile area 123c. Read the profile. Then, the CPU 120 refers to the technical level for each step of the performer stored in the “first look master degree” of the profile, selects any practice step from the three practice steps shown in FIG. The basic performance information and score information read from the practice song database 123a are adjusted according to the selected step and the level of the step, that is, the constituent sounds are reduced.
[0049]
When the performer executes the performance processing program for the first time, the selected practice music is not adjusted, and the process proceeds to the next process while maintaining the original music. Further, in this case, a first profile area 123c and a second profile area 123d are newly created for the music piece of the performer, and each item in both profile areas created after the end of the first performance corresponds to the performance. Data will be written.
[0050]
Further, the CPU 120 refers to the “miss key”, “key-on time”, “key time”, and “velocity” for each phrase stored in the first profile area 123c, and notes about the notes in the music that are expected to miss. Adjusts the musical score display data by appropriately selecting the “display pattern” for teaching. The “display picture” selection method here is performed with reference to the player's profile stored in the second profile area 123d. In other words, the second profile area 123d stores information on how the level of the displayed picture of each “display picture” is reflected on the performance. The “display pattern” is determined in consideration of the information and the expected amount of mistakes in the first profile area 123c. For example, for items such as “key-on time”, “key time”, and “velocity”, a deviation from the value to be originally played is obtained from the “average value” in the first profile area 123c, and this is used as an expected amount of mistake. What is necessary is just to determine the level of the “display pattern” that provides the response amount closest to the expected amount, that is, the teaching content. The adjusted data adjusted in this way is written by the CPU 120 into the performance recording area 123b.
[0051]
In addition, the CPU 120 displays a score based on the score display data adjusted as described above on the display unit 124 (step Sa4). Here, FIG. 10 is a diagram partially showing an example of a score display adjusted according to the technical level of the performer. As shown in the figure, in the present embodiment, the past performance contents by the performer are analyzed by the adjustment as described above, and technical characteristics and habits when playing this music are taken into account, and an accurate performance is performed. The notes to which arrows and color changes are added are displayed on the staff, so that the score display and the teaching information about each note are displayed together. Note that fingering information, which is information such as which finger is used to press the key, may be displayed on the display unit 124.
[0052]
As described above, when a musical score display process in which notes or the like transformed for teaching according to the technical characteristics of the performer are arranged on the staff score is executed, the CPU 120 shifts to a standby state for the performance start by the performer. Then, it is determined whether or not the performance has been started (step Sa5). The determination method here may be, for example, a determination method of displaying a performance start soft button and displaying whether or not the performance start soft button is clicked when displaying the score. Further, when the key sensor 25 detects that the player has pressed the key 1 with the piano 11, and the detection result is input from the piano 11 to the CPU 120 of the PC 10, it may be determined that the performance has started. .
[0053]
If it is determined that the performance has started (determination “YES” in step Sa5), the CPU 120 uses the operation information of the key 1 acquired by the key sensor 25 according to the performance of the performer (ie, pressing operation of the key 1) to the control unit. 30 and through the communication interface 128, performance information corresponding to the performance by the performer is recorded in the performance recording area 123b (step Sa6). During the recording process, the CPU 120 specifies a position of the music piece that the player is currently playing based on key pressing operation information sequentially supplied from the piano 11 according to the player's performance. As shown in FIG. 11, each of the key pressing operation information supplied from the piano 11 one by one by the performance by the performer is changed to the music to be originally played (if adjusted, The note to which the adjusted music) corresponds is specified. Then, the key pressing operation information by the performer (information indicating the key number pressed, the key pressing start time, the key pressing time, and the key pressing force) associated with each musical note constituting the music to be originally played is specified. Is recorded in the “actual performance information” area of the performance recording area 123b.
[0054]
In this way, in order to record each key pressing operation information supplied from the piano 11 in association with each note constituting the music to be originally played, the key pressing supplied from the piano 11 as described above is recorded. It is necessary to perform a performance trace process that accurately specifies which position of the music piece the player is playing from the operation information.
[0055]
In the performance trace processing performed in the present embodiment, a note string to be originally played is searched based on key number (pitch) data included in the key pressing operation information supplied from the piano 11, and a matching portion (candidate) is searched. Performance of finding → Note-trace processing, which is the task of detecting matching of music score, and finding out the note that will be played soon among the notes that should be played, and inputting the key press operation information including key number information corresponding to this note It is performed in both directions of time scale trace processing, which is a task of detecting matching of musical score → performance that is waiting.
[0056]
First, note trace will be described. This is based on the key number information (pitch) included in the key pressing operation information sequentially supplied from the piano 11, and a pitch sequence is generated as a pattern. This is to detect matching with a note sequence of (later music piece).
[0057]
A note trace processing method will be specifically described with reference to FIG. In this example, it is assumed that the musical note data string of the musical score data is aligned with Doremid Milled and Millemi Sofa Red. This figure is an example of the case where the fifth sound is played from the beginning and played without mistouch. That is, it is an example in the case where “Mired ...” is played. In this embodiment, the performance location can be detected even when the performance is replayed in the middle of practice.
[0058]
First, “mi” is input as the first key number information. When a note that matches “mi” is searched from a note string to be originally played, the third sound, the fifth sound, the eighth sound, and the tenth sound correspond to this. The positions of the third sound, the fifth sound, the eighth sound, and the tenth sound are stored as current position candidates 221, 222, 223, and 224, respectively. When the input key number information matches the next note (fourth sound, sixth sound, ninth sound, eleventh sound), this candidate 2 moves to that position.
[0059]
The candidate data of each candidate is composed of “note position / number of matched notes / number of mismatched notes / number of consecutive matches / number of consecutive mismatches”, and is updated each time new key number information is input. The note position indicates on which note string this candidate is currently located. The number of matching notes is the number of input key number information that matches the note string. The number of mismatch notes is the number of input pitch data that did not match the note data string. The number of consecutive matches is a number indicating how many times the input key number information matches continuously when it matches the note string. The consecutive mismatch number is a number indicating how many consecutive mismatches occur when the input pitch data does not match the note data string.
[0060]
Since the candidates 221 to 224 match only the first sound, the candidate data are “third sound / 1/0/1/0” and “fifth sound / 1/0/1/0”, respectively. "8th sound / 1/0/1/0" and "10th sound / 1/0/1/0".
[0061]
“Re” is input as key number information for the next performance. Each of the candidates 221 to 224 is inspected to determine whether the next note is “R”. Then, since the next note after the candidate 222 and the candidate 223 is “L”, the note position of these candidates is moved to the position of this note, and the candidate data is updated. The candidate 222 is “sixth sound / 2/0/2/0”, and the candidate 223 is “9th sound / 2/0/2/0”. On the other hand, the candidates 221 and 24 do not coincide with the key number information because the next note data is not “L”, the candidate 221 becomes “third note / 1/1/0/1”, and the candidate 224 becomes “tenth note / 1/1/0/1 ".
[0062]
Next, when searching for the note data of “L” for which the existing candidate has not moved, the second sound and the thirteenth sound are present. Let these be candidates 225 and 226 as candidates for new current positions. The candidate 225 is “second sound / 1/0/1/0”, and the candidate 226 is “13th sound / 1/0/1/0”.
[0063]
Furthermore, since “do” is input as the next key number information, it is inspected for the candidates 221 to 226 whether the next note is “do”. Since the next note after candidate 221, candidate 222, and candidate 226 is "do", the note position of these candidates is moved to the position of this note, and the candidate data is updated. Candidate 221 is “fourth note / 2/1/1/0”, candidate 222 is “seventh note / 3/0/3/0”, and candidate 226 is “14th note / 2/0/2/0”. It becomes.
[0064]
In addition, the candidates 223 to 225 are, respectively, the candidate 223 is “9th sound / 2/1/0/1”, the candidate 224 is “10th sound / 1/2/0/2”, and the candidate 225 is “second” Sound / 1/1/0/1 ". Next, when searching for note data of an existing candidate that has not moved, the first sound is present. This becomes candidate 227 “first sound / 1/0/1/0” as a new candidate of the current position.
[0065]
Thus, the candidate 222 indicating the current point that is the correct performance position has a large value for both the number of matches and the number of continuous matches, and the number of mismatches is small (0). Thus, the correct current point can be determined by examining the candidate 2 data. Even in the case of inconsistency, the reason why the number of inconsistencies is stored while not being deleted immediately is to cope with the case where the performer mistouches and inputs an incorrect sound. That is, even if the performer makes a mistouch, the number of inconsistencies increases only by one, and does not greatly hinder the determination of the correct current point. For example, even if “Mirered ...” is played as “Mirered ...”, the candidate 222 becomes “Seventh sound / 3/1/2/0”, which is also a powerful current point. Is a candidate. If the performer makes a mistake or skips the sound, the correct candidate shown in this figure is started from the next sound.
[0066]
Next, time scale trace processing will be described. The candidate of the current point is narrowed down to several by the above note trace processing. One note is extracted from each of the narrowed candidates, and it waits for key number information that matches the note to arrive near a predetermined time. Based on the key number information that arrives at this time, it determines which candidate is the actual current point, extracts the tempo based on the arrival timing, and predicts the current point by matching the time signature of the score data. Let
[0067]
FIG. 13 is a flowchart showing the operation of the time scale trace process. In the time scale trace process, the process waits until candidate 2 is determined by the above-described note trace process (step Sb1). When a candidate is determined by the note trace process, a key number of a note that will be supplied from the piano 11 next is predicted based on this candidate and a note string of a music to be originally played (step Sb2). Then, when the player advances the performance and the next key number information is supplied from the piano 11, it is determined whether or not the key number information matches the predicted pitch (step Sb3). Here, when the supplied key number information matches the key number of the predicted note (step Sb4), the key pressing operation information including the supplied key number information becomes the predicted note in the music to be originally played. It can be specified that it corresponds (step Sb5).
[0068]
In the present embodiment, by the performance trace process in which the above-described note trace process and time scale trace process are performed in both directions, the correspondence between the key depression operation information sequentially supplied from the piano 11 and the musical notes of the music to be originally played. The attachment can be performed more accurately.
[0069]
While the performance is being performed by the performer, the key pressing operation information by the performance is sequentially input from the piano 11 to the CPU 120 of the PC 10, and the music to be performed by the performance trace processing as described above, that is, the adjusted practice music. Is recorded in the performance recording area 123b in association with one of the notes constituting the.
[0070]
When it is determined that the performance has been completed by the performance trace process (step Sa6), the CPU 120 performs performance information corresponding to the performance of the performer recorded in the performance recording area 123b and adjustments stored in the performance recording area 123b. The post-practice music information (performance information serving as an example of this performance) is used to perform an evaluation process for the performance (step Sa8), and the stored contents of the first profile area 123c and the second profile area 123d are updated.
[0071]
Here, a method of updating the first profile area 123c and the second profile area 123d will be described. First, a method for updating the first profile area 123c will be described with reference to FIG. FIG. 14 is a diagram showing a concept of a process for updating a phrase with a musical piece for which performance practice has been performed. The update of the first profile area 123c is performed for each phrase, and information on items such as “key”, “key-on time”, “key time”, and “velocity” is modeled song information and performance information. Compared with information (performance music information) by performance actually performed by the person. Here, as shown in the drawing, the phrase to be processed is changed to “do” (MIDI note number = 60) → “re” (MIDI note number = 62) → “mi” (MIDI note number = 64) → “do” (MIDI). A case of being composed of quarter notes (tempo value = 120, velocity value = 64) such as note number = 60) will be described.
[0072]
As shown in the figure, the “evaluation result” compares the practice song information of “key”, “key-on time”, “key time”, and “velocity” with the performance song information, and the result is the performance evaluation. More specifically, in the case of “key”, the coincidence / non-coincidence of the note numbers of the practice music information and the performance music information is evaluated, and in the case of the mismatch, the difference between the MIDI note numbers is evaluated as a numerical value. In the example shown in the figure, the last “do” is to be pushed when “re” is pushed. In this case, 62 (re) −60 (do) = + 2. Note that the sound of “do” indicated by “−” in the figure indicates a sound that is adjusted (reduction of constituent sounds) in this step and does not need to be played. Such a sound is unconditionally evaluated as “◯”.
[0073]
Next, in the case of “key-on time”, the ratio of the actual key-on timing to the timing (120 in the figure) shown in the practice song information is calculated as a percentage. Here, the numerical value described in the “key time” in the practice song information and the performance song information is the time between the start timing of the previous note (key press), and the above ratio is calculated using this time. calculate. As for the “key time”, as in the “key-on time”, the ratio of the actual key pressing time to the sound length indicated in the practice song information is calculated as the evaluation value. As for “velocity”, the ratio of the key pressing force (velocity value) by the actual performance to the strength (velocity value) indicated in the practice song information is calculated as the evaluation value in the same way as “key-on time” and “key time”. Is done.
[0074]
Further, an average value in the phrase is also calculated from the evaluation values calculated for each note in the evaluation of “key-on time”, “key time”, and “velocity”. Such performance evaluation of the performer this time is performed for each phrase, and each data in the first profile area 123c shown in FIG. 6 is updated according to the following procedure based on the evaluation result.
[0075]
First, the numerical value of the item “number of evaluations” in the first profile area 123c is incremented by one. Then, “Recent Value” for “Miskey” is updated to the above evaluation result, and when the evaluation result is “◯”, “Success Count” is incremented by one. In addition, the “recent value” and the “average value” are also updated for “key-on time”, “key time”, and “velocity” based on the evaluation result of this time. If the current performance is the first performance, the current evaluation result is written in each area of the first profile area 123c newly created as described above. In this way, each data stored in the first profile area 123c is updated. The “first-look master level” in the first profile area 123c is updated when teaching and adjustment details are determined (step Sa11).
[0076]
Next, a method for updating the second profile area 123d will be described with reference to FIG. The update of the second profile area 123d includes the evaluation result of the previous performance for each phrase, the evaluation result of the current performance (see FIG. 14), and information indicating the “display pattern” displayed at the time of the current performance. Based on. Specifically, first, each item of the evaluation result of the previous performance is compared with each item of the evaluation result of this performance, and each item “key”, “key-on time”, “key time” and For “velocity”, the amount of change from the previous time to the current time, that is, the response amount reflected in the current performance is calculated (step A). Then, the change amount of each item calculated in this way is associated with the “display pattern” displayed for each item at the time of the current performance, and the display pattern for the current performance, that is, the correspondence between the teaching content and the response amount (Step B). The correspondence between the teaching content and the response amount for the current performance obtained in this way is reflected in the content of the second profile area 123d already created based on the past performance content and teaching content. The player's profile stored in is updated.
[0077]
More specifically, when the level 2 pattern is displayed for the item “key-on time”, the response amount is 10, and the “key-on time” in the current second profile area 123d (see FIG. 8) is displayed. When the “display count” of the “display pattern” of level 2 is n and the “response amount (average)” is m, the “display count” is n + 1, and the “response amount (average)” is (m * n + 10) / (n + 1) ) Is updated.
[0078]
When the updating process of the first profile area 123c and the second profile area 123d based on the evaluation process and the result of the evaluation process is completed, the CPU 120 determines whether or not the player's practice step may be increased. (Step Sa9). Here, the evaluation result created in the update process of the first profile area 123c described above is compared with a preset numerical value or the like, and it is determined whether or not this player may be stepped up.
[0079]
Here, FIG. 16 shows an example of step-up determination processing. As shown in the figure, in the step-up determination, first, it is determined whether or not the level in the practice step before the current performance is 3 (step Sc1). If the level is other than level 3, step-up determination is not performed and step maintenance is determined. On the other hand, if it is determined in step Sc1 that the level is level 3, it is determined whether or not the miskey rate of the current performance is equal to or less than a predetermined value (10%) (step Sc2). Here, if the miskey rate is less than or equal to a predetermined value, the values of items such as “key-on time”, “key time”, and “velocity” are within a predetermined range (for example, between 90% and 110%). ) Is determined whether or not there are more than a predetermined number of items (for example, two or more of three items) (step Sc3). Is done. Further, when the determinations at step Sc2 and step Sc3 are “NO”, step-up maintenance is determined.
[0080]
Here, the step-up determination performed by the CPU 120 may be used only as a guideline, and a determination result as a guideline may be displayed on the display unit 124 so that the player can select whether or not the final step-up is possible.
[0081]
When the step-up determination is completed, the CPU 120 determines whether or not the final step (practice step 9 shown in FIG. 7) for this practice song has been completed as a result of the determination (step Sa10). As a result, when the final step is finished, the performance teaching processing program is finished. Here, without ending the program, the process may return to step Sa1 to prompt the user to select another practice song.
[0082]
On the other hand, if it is determined as a result of the determination at step Sa10 that the final step has not been completed, the CPU 120 determines the adjustment contents and the teaching contents of the practice music according to the determined practice step, and the performance recording area 123b. (Step Sa11).
[0083]
When determining such adjustment contents, the “first-look master degree” in the first profile area 123c is referred to. Before that, the item data of “first-look master degree” is updated according to the performance contents of this time. The level is selected according to the content of the updated “first-look master degree”, and the content of reduction in the number of constituent sounds is determined. Here, an example of a method for updating the “first-look master degree” will be described with reference to FIG. First, it is determined whether or not the level in the practice step when performing this time is 1 or 2 (step Sd1). Here, if the level is 1 or 2 (determination “YES” in step Sc1), it is determined whether or not the miskey rate, that is, the probability of a key press error is not more than a predetermined value (for example, 15%). (Step Sd2). Here, when the miskey rate is less than or equal to a predetermined value, the values of items such as “key-on time”, “key time”, and “velocity” are within a predetermined range (for example, between 90% and 110%). It is determined whether or not there are more than a predetermined number of items (for example, two or more of three items) (step Sd3). If there are more than a predetermined number of items within a predetermined range, the level is increased within the step. Then it is determined. Therefore, for example, when the level before the performance this time is 1, it is updated to level 2. In addition, when the determination in step Sd2 and step Sd3 is “NO”, the current level is maintained.
[0084]
On the other hand, if the current level is not 1 or 2, that is, level 3 in the determination in step Sd1, it is determined whether or not the miskey rate is greater than or equal to a predetermined value (step Sd4). Here, when the miskey rate is equal to or higher than a predetermined value (for example, 10%), it is determined that the level is lowered within the step, that is, the level is lowered to level 2. On the other hand, when the miskey rate is less than the predetermined value in the determination in step Sd4, out of the predetermined range (eg, 80% to It is determined whether or not there are more than a predetermined number of items (excluding 120%) (for example, two or more of three items) (step Sd5), and if there are more than a predetermined number of items within the predetermined range, step It is determined that the level is down, that is, down to level 2. On the other hand, when the determination in step Sd5 is “NO”, the current level, level 3, is maintained.
[0085]
In addition, in the adjustment content and teaching content determination process, each note used for the score display is more accurately played by the performer based on the updated contents of the first profile area 123c and the second profile area 123d. “Display picture” that can be selected. Then, the CPU 120 displays a score reflecting this adjustment content on the display unit 124, and then waits for the performance start by the performer to determine whether or not the performance has started (step Sd5).
[0086]
As described above, in this embodiment, when a performer performs a performance of a certain piece of music, the music is adjusted to the content corresponding to the player's performance skill level (reduction of constituent sounds), and the player's current time Provides an environment that is easy to practice at the technical level of For example, in the case of a beginner, there may be a case where a sufficient effect may not be obtained even if many original songs without sudden reduction of the constituent sound are practiced. Perform step-by-step practice of reducing the number of sounds and adjusting to a song that is easy to practice, and practicing the performance, and gradually practicing a song that is closer to the original with a reduced number of compositional sounds as the technical level improves Can be practiced effectively.
[0087]
Further, in the present embodiment, in accordance with the past performance contents of the performer, a portion in which a performance error is expected in the music is detected, and a display pattern that prompts teaching that the error does not occur is selected and displayed on the score. Will be added to the expected note. Here, multiple levels of teaching steps are set for the display pattern, and when the expected level of mistakes is large, a display that greatly calls attention is given, and when the level of expected mistakes is small Is set according to the amount of prediction error, such as a small warning. Moreover, the expected amount of mistakes was analyzed by the player's past performance, and the teaching content (display pattern) for correcting the predicted mistake amount is also a response amount to the player's past teaching content. Based on the decision. That is, in the present embodiment, the teaching contents that match the performer are selected and displayed in consideration of technical features and habits based on the performer's past performance and the like. Therefore, the performer can perform an effective performance by referring to the teaching content displayed on the display unit 124.
[0088]
C. Modified example
In addition, this invention is not limited to embodiment mentioned above, Various deformation | transformation which is illustrated below is possible.
[0089]
(Modification 1)
In the embodiment described above, the first profile area 123c and the second profile area 123d in which the player's profile is stored in the hard disk 123 of the PC 10 are prepared, and the case where the present invention is applied to the PC 10 and the piano 11 has been described. As shown in FIG. 18, the present invention can be applied to a network system.
[0090]
As shown in the figure, this network system includes a PC 310 connected to the Internet 300 via a telephone network 302, a server 301 connected to the Internet 300, and a piano 311 connected to the PC 310.
[0091]
Here, the piano 311 has the same configuration as that of the piano 11 in the above-described embodiment, and when the performance teaching process is executed, the key pressing operation information is sequentially output to the PC 310 in accordance with the key pressing operation by the player. In addition to the same configuration as the PC 10 in the above embodiment, the PC 310 is equipped with an interface (for example, a modem or a terminal adapter) for connecting to the Internet 300 via the telephone network 302. The PC 310 has browser software (for example, Microsoft Internet Explorer) installed on its hard disk for data communication with various nodes connected to the Internet 300, and starts the browser. Thus, the PC 310 can access the server 301 via the telephone network 302 and the Internet 300 and exchange data with the server 301.
[0092]
The difference between this modified example and the above embodiment is that the hard disk of the PC 310 includes the practice song database 123a, the first profile area 123c, and the second profile area 123d stored in the hard disk 123 of the PC 10 of the above-described embodiment. It is not stored, and these various data are stored in the server 301. When the PC 310 performs the same performance teaching process as the PC 10 of the above-described embodiment, the data stored in the practice song database 123a, the first profile area 123c, and the second profile area 123d are required.
