Description

  The present invention relates to a technique for evaluating music.

  Conventionally, a subjective evaluation by a performer or the like has been performed in evaluating the difficulty level when playing music. In order to perform a more objective evaluation, a technique for calculating a difficulty level when playing with a keyboard instrument by a predetermined method has been developed. For example, according to the technique disclosed in Patent Document 1, the degree of difficulty of a song is calculated using information such as fingering designated for each sound for a song played with a keyboard instrument.

JP 2010-281881 A

  According to the technique disclosed in Patent Document 1, in order to calculate the degree of difficulty of music, various information is required in addition to information on the pitch of each sound of the music. For example, due to the fact that the performance of a musical piece by a keyboard instrument is very complicated, for example, fingering designated for each sound of the musical piece needs to be prepared in advance. That is, such a technique can only calculate the degree of difficulty on the premise of playing a musical instrument with a keyboard instrument.

  On the other hand, depending on the type of music, the performance of the music is not limited to being performed with a keyboard instrument. For example, when playing a melody part composed of a single note, it is possible to perform using various musical instruments. For example, a wind instrument is basically played using a single sound, but the same melody can be played with various types of wind instruments. At this time, the difficulty level for one piece of music may differ depending on the type of musical instrument to be played. This is because the playing method varies depending on the type of musical instrument. Thus, no technique has been developed for calculating the degree of difficulty of a musical piece in relation to the musical instrument to be played and the musical piece.

  One of the objects of the present invention is to calculate an evaluation value for a music corresponding to the type of musical instrument to be played.

  According to one embodiment of the present invention, with reference to evaluation criterion information that defines an evaluation value for pitch transition for a predetermined instrument type, an adjacent sound with respect to a sound included in a musical composition defined in the pronunciation control data An evaluation value is calculated on the basis of the transition relationship, and a music evaluation device is provided that includes a calculation unit that calculates a music evaluation value for the music based on the evaluation value, and an output unit that outputs the music evaluation value Is done.

  When the type of the musical instrument is a woodwind instrument, the evaluation value defined in the evaluation reference information may be determined based on a change in the open / close state of each hole of the woodwind instrument at the time of transition of the pitch.

  When the instrument type is a valve-type brass instrument, the evaluation value defined in the evaluation reference information may be determined based on a change in the state of the brass instrument valve at the time of the transition of the pitch. .

  When the instrument type is a slide-type brass instrument, the evaluation value defined in the evaluation reference information may be determined based on a change in the slide state of the brass instrument at the time of transition of the pitch. .

  The evaluation value defined in the evaluation reference information may be determined further based on a change in the order of harmonics of the musical instrument when the pitch is shifted.

  When the type of the instrument is a stringed instrument having a fingerboard, the evaluation value defined in the evaluation reference information is based on a change in the fingerboard longitudinal direction at a position where the string of the stringed instrument is pressed at the time of transition of the pitch. It may be decided.

  The evaluation value defined in the evaluation reference information may be determined further based on a movement amount between strings at a position where the string is pressed when the pitch is shifted.

  The information processing apparatus further includes a specifying unit that specifies a predetermined type from a plurality of instrument types, the evaluation reference information defines the evaluation value for each type of instrument, and the calculation unit determines the type of the specified instrument. The music evaluation value may be calculated with reference to the corresponding evaluation criterion information.

  In the evaluation value for the transition of the pitch, the first evaluation value when the transition from the first pitch to the second pitch and the second when the transition from the first pitch to the third pitch are performed. When the musical instrument type is the first type, the first evaluation value may be large, and when the musical instrument type is the second type, the second evaluation value may be large.

  Further, according to one embodiment of the present invention, with reference to the evaluation standard information that defines an evaluation value for pitch transition for a predetermined instrument type, with respect to the sound included in the musical composition defined in the pronunciation control data An evaluation value is calculated based on the transition relationship with the adjacent sound, a music evaluation value for the music is calculated based on the evaluation value, a music evaluation value for the music is calculated based on the evaluation value, and the music evaluation A music evaluation method is provided that includes outputting a value.

  According to one embodiment of the present invention, the sound included in the music defined in the sound generation control data is referred to the evaluation standard information that defines the evaluation value for the shift of the pitch for the predetermined instrument type. Calculating an evaluation value based on the transition relationship with the adjacent sound, calculating a music evaluation value for the music based on the evaluation value, calculating a music evaluation value for the music based on the evaluation value, A program for executing output of the music evaluation value is provided.

  According to one embodiment of the present invention, an evaluation value for a music piece can be calculated corresponding to the type of musical instrument to be played.

  The control unit 11 includes an arithmetic processing circuit such as a CPU. The control unit 11 causes the CPU to execute the application program stored in the storage unit 13 to realize various functions in the music evaluation device 1. Various functions include a music evaluation function described below. The storage unit 13 is a storage device such as a nonvolatile memory or a hard disk. The storage unit 13 stores an application program for realizing the music evaluation function. The application program only needs to be executable by a computer, and is downloaded via a network in this example. The application program may be provided in a state stored in a computer-readable recording medium such as a magnetic recording medium, an optical recording medium, a magneto-optical recording medium, or a semiconductor memory. In this case, the music piece evaluation apparatus 1 should just be provided with the apparatus which reads a recording medium.

  The operation unit 15 is a device to which an operation by a user is input, such as a touch sensor, and outputs a signal corresponding to the input operation to the control unit 11. The operation unit 15 can input various operations required for the music evaluation function such as selection of the type of musical instrument to be evaluated. The display unit 17 is a display device such as a liquid crystal display or an organic EL display, and displays a screen based on control by the control unit 11. The communication unit 19 is connected to a communication line such as the Internet based on the control of the control unit 11 and transmits / receives information to / from an external device.

[Music evaluation function]
The music evaluation function realized by the control unit 11 of the music evaluation apparatus 1 executing the application program will be described. A part or all of the configuration for realizing the music evaluation function described below may be realized by hardware.

  FIG. 2 is a block diagram showing the configuration of the music evaluation function in the embodiment of the present invention. The music evaluation function 100 is realized by each configuration of the acquisition unit 101, the specification unit 103, the calculation unit 105, and the output unit 107. 2 is expanded in the storage unit 13 by executing the program. Note that the evaluation criterion information 121 may be acquired by the calculation unit 105 from the external device via the communication unit 19.

  The acquisition unit 101 acquires data related to the music to be evaluated. This data is sounding control data that defines the sounding content of the music for each sound, and in this example, is MIDI format sequence data. In this example, the sound generation control data only needs to define the arrangement order of the sounds included in at least the sound generation content of the music.

  The specifying unit 103 specifies the type of musical instrument that is a target for calculating the difficulty level. The type of the instrument is selected by a user input operation on the operation unit 15. As described above, the types of musical instruments to be selected are trumpet, trombone, alto saxophone and violin in this example.

  The evaluation criterion information 121 is stored in the storage unit 13 corresponding to each of the types of musical instruments to be selected. The evaluation criterion information 121 includes a fingering table 123 and a difficulty level calculation method 125. The fingering table 123 is a table that defines fingering information for a pitch to be pronounced. The difficulty level calculation method 125 is information that defines the calculation method when calculating the difficulty level using the fingering table 123 as described later. First, the fingering table 123 corresponding to each instrument type will be described with reference to FIGS.

  FIG. 3 is a diagram illustrating a fingering table (trumpet) in the embodiment of the present invention. The fingering table corresponding to the trumpet is a table in which the order of harmonics (sometimes referred to as mode) and fingering are associated with the pitch. In FIG. 3, “pitch” is “key number” (may be referred to as note number) expressed in MIDI format, and the note name is shown as “note” for reference. The same applies to “pitch” even if it is placed on the fingering table of another musical instrument. In “fingering”, “A” to “C” correspond to three piston valves, and “1” indicates a state where the piston is pressed. For example, for “C # 3”, the order of harmonics is “1”, indicating that all piston valves are depressed.

  FIG. 4 is a diagram illustrating a fingering table (alto saxophone) according to the embodiment of the present invention. The fingering table corresponding to the alto saxophone is a table in which fingering is associated with the pitch. In FIG. 4, in “fingering”, “A” to “F” correspond to the keys pressed with the left hand, and “G” to “K” correspond to the keys pressed with the right hand. When the corresponding hole is opened / closed by the key, “1” is closed and “0” is opened. For example, “C # 3” indicates a state in which the “C key” and the “B key” are operated and the holes corresponding to these keys are closed.

  FIG. 5 is a diagram illustrating a fingering table (trombone) according to the embodiment of the present invention. The fingering table corresponding to the trombone is a table in which the harmonic order and position are associated with the pitch. In FIG. 5, “Position” represents the position of the slide tube, “1” corresponds to the position where the support column is closer to the mouthpiece side (position where the tube length is shortened), and “7” is the support column from the mouthpiece. Corresponds to a distant position (position where the tube length becomes longer). For example, “C # 3” indicates a state in which the order of the harmonic is “1” and the slide tube is positioned at the position “5”. The trombone of a brass instrument is generally referred to as a finger position, not a fingering, but in this application, for the sake of consistency with other instruments, it is described as a “fingering table” for convenience. Further, as described with reference to FIG. 5, the same applies to musical instruments called other finger positions.

  FIG. 6 is a diagram illustrating a fingering table (violin) in the embodiment of the present invention. A fingering table corresponding to a violin is a table in which strings and fingerboard positions are associated with pitches. In FIG. 6, “string” represents the type of string, and “1” to “4” correspond to the first string (E line) to the fourth string (G line). The “fingerboard position” represents a position in the fingerboard longitudinal direction where the string is to be pressed, “1” corresponds to a position closer to the peg, and “14” corresponds to a position closer to the piece. For example, “C # 3” indicates a state in which the fingerboard position corresponding to “6” is pressed among the strings of the E line.

  Returning to FIG. 2, the description will be continued. The difficulty level calculation method 125 corresponding to each instrument type varies slightly depending on the contents of the fingering table 123 described above, and details thereof will be described later.

  The calculation unit 105 reads the evaluation criterion information 121 corresponding to the instrument type specified by the specifying unit 103. Further, the calculation unit 105 calculates the difficulty level (music difficulty level) for the music specified in the pronunciation control data acquired by the acquisition unit 101 based on the evaluation reference information 121. At this time, the calculation unit 105 calculates the difficulty level (each sound difficulty level) based on the transition relationship from the immediately preceding adjacent sound with respect to the sound included in the music, and the music difficulty level based on each sound difficulty level. Calculate the degree. The basic music difficulty calculation method is almost the same regardless of the type of musical instrument, but the specific calculation method is different due to the difference in fingering. A detailed calculation method will be described later.

  The output unit 107 outputs information (music difficulty level information) according to the music difficulty level calculated by the calculation unit 105. The music difficulty level information is associated with information indicating the type of musical instrument specified by the specifying unit 103. The outputted music difficulty level information can be used in various ways. For example, the music difficulty level information is associated with the pronunciation control data acquired by the acquisition unit 101, for example. If it does in this way, it can also be used for the performance evaluation apparatus with respect to playing a musical instrument along the music of pronunciation control data. For example, the performance evaluation device receives an input of a musical instrument type, refers to the music difficulty level information, acquires a musical difficulty level determined for the musical instrument type, and obtains a musical instrument according to the musical difficulty level. What is necessary is just to change the grade (increase / decrease of basic score, severity of evaluation criteria) of the influence on scoring on performance. The above is the description of the music evaluation function 100.

[Evaluation process]
A music evaluation method using the evaluation process by the music evaluation function 100 described above will be described with reference to FIG.

  FIG. 7 is a diagram for explaining music evaluation processing in the embodiment of the present invention. In the music evaluation device 1, when the user designates a music piece (music control data) to be evaluated by an input operation via the operation unit 15, the music control data is acquired by the acquisition unit 101, and the music is evaluated. Processing is executed. First, the specifying unit 103 performs a display on the display unit 17 that prompts the user to select an instrument to be evaluated. When the user selects a musical instrument from the options by an input operation via the operation unit 15, the specifying unit 103 specifies the selected musical instrument as the type of musical instrument for which the difficulty level is to be calculated (step S101). The calculation unit 105 acquires evaluation criterion information corresponding to the specified instrument type from the storage unit 13 (step S103).

  First, the calculation unit 105 initializes “n” indicating the order of sounds included in the music (n = 0) (step S105), and adds “1” to “n” (n = n + 1) (step S105). S107). That is, in this process, the sound of the music is advanced. The calculation unit 105 acquires the pitch Pn corresponding to the nth sound included in the music from the music control data (step S109). The calculation unit 105 refers to the fingering table 123 in the evaluation criterion information 121, and acquires fingering information F (n) corresponding to the pitch P (n) (step S111). The content of this fingering information F (n) differs depending on the type of instrument specified in step S101. The calculation unit 105 determines whether n = 1 (first sound) (step S113). If n = 1 (step S113; Yes), the calculation unit 105 returns to step S107 and continues the processing. On the other hand, when n = 1 is not satisfied (step S113; No), n is determined based on the fingering information F (n) and the fingering information F (n−1) acquired for the sound before that. Each sound difficulty level D (n) for the second sound is calculated (step S115). The calculation method of each sound difficulty level D (n) is defined in the evaluation standard information 121 as the difficulty level calculation method 125, and differs depending on the type of musical instrument. Details of the calculation method of each sound difficulty level D (n) corresponding to each instrument will be described later.

  The calculation unit 105 calculates an integrated value MP (MP = MP + D (n)) of each sound difficulty level D (n) (step S117). The calculation unit 105 determines whether the value of “n” corresponds to the final sound of the music (step S119). If the value of “n” does not correspond to the final sound of the music (step S119; No), the process returns to step S107 and continues. On the other hand, when the value of “n” is the final sound of the music (step S119), that is, when there is no next sound in the music, the calculation unit 105 calculates the integrated value MP as the music difficulty level and outputs it. The unit 107 outputs the integrated value MP as the music difficulty level (step S121). As a result, the evaluation process ends.

[Calculation method for each sound difficulty]
A specific example for each type of musical instrument will be described with respect to a method of calculating each sound difficulty level D (n) in the above evaluation process.

[Calculation method of trumpet sound difficulty]
The fingering information F (n) in the case of the trumpet includes the harmonic order M (n) and fingering Xb (n) = {FA (n), FB (n), FC (n)}. FA (n) to FC (n) correspond to fingerings “A” to “C” in the table illustrated in FIG. The state of the first piston valve is shown at the pitch P (n). Similarly, FB (n) and FC (n) correspond to the state of the second piston valve and the state of the third piston valve. According to the table illustrated in FIG. 3, each parameter can take the following values. M (n) can take “1” to “6”. FA (n), FB (n), and FC (n) can all be “0” or “1”. That is, the fingering X (n) has 3-bit information by FA (n), FB (n), and FC (n).

  In this example, each sound difficulty level D (n) for the nth sound is the harmonic overtone when the pitch P (n−1) of the immediately preceding adjacent sound shifts to the nth pitch P (n). It is calculated based on the change amount of the order and the change amount of fingering. The amount of change in the overtone order is represented by, for example, | M (n) −M (n−1) |. The amount of fingering change corresponds to the number of bits that are “false” when “Xb (n) XOR Xb (n−1)” is calculated, and can take a value from “0” to “3”. . Note that the amount of change in the order of harmonics may not be used for calculating each sound difficulty level D (n).

Specifically, each sound difficulty level D (n) of the trumpet is calculated by the following equation.
D (n) = {M ( n) -M (n-1)} 2/2 + | FA (n) -FA (n-1) | + | FB (n) -FB (n-1) | + | FC (n) -FC (n-1) |

[Alto saxophone sound difficulty calculation method]
Fingering information F (n) in the case of alto saxophone includes fingering Xk (n) = {FA (n), FB (n),..., FK (n)}. FA (n) to FK (n) correspond to fingerings “A” to “K” in the table illustrated in FIG. According to the table illustrated in FIG. 4, all of FA (n) to FK (n) can take “0” or “1”. That is, the fingering X (n) has 11 bits of information by FA (n) to FK (n).

  In this example, each sound difficulty level D (n) for the nth sound is fingering when the pitch P (n-1) of the immediately preceding adjacent sound shifts to the nth pitch P (n). It is calculated based on the amount of change. The amount of change in fingering corresponds to, for example, the number of bits that are “false” when “Xk (n) XOR Xk (n−1)” is calculated, and can take values from “0” to “11”. . Note that the amount of change in the order of harmonics may not be used for calculating each sound difficulty level D (n).

Specifically, each sound difficulty level D (n) of the alto saxophone is calculated by the following equation.
D (n) = | FA (n) −FA (n−1) | + | FB (n) −FB (n−1) | +... + | FK (n) −FK (n−1) |

[Calculation method for each sound difficulty of trombone]
The fingering information F (n) for the trombone includes the harmonic order M (n) and the fingering (position) Xp (n). According to the table illustrated in FIG. 5, each parameter can take the following values. M (n) can take “1” to “7”. Xp (n) can take “1” to “7”.

  In this example, each sound difficulty level D (n) for the nth sound is the harmonic overtone when the pitch P (n−1) of the immediately preceding adjacent sound shifts to the nth pitch P (n). It is calculated based on the change amount of the order and the change amount of the fingering (position). The amount of change in the overtone order is represented by, for example, | M (n) −M (n−1) |. The amount of fingering change is represented by, for example, | Xp (n) −Xp (n−1) |. Note that the amount of change in the order of harmonics may not be used for calculating each sound difficulty level D (n).

Specifically, each sound difficulty level D (n) of the trombone is calculated by the following equation.
D (n) = {M ( n) -M (n-1)} 2/2 + {Xp (n) -Xp (n-1)} 2/5

[Calculation method of each sound difficulty of a violin]
Fingering information F (n) for a violin includes a string type S (n) and a fingering (fingerboard position) Xs (n). According to the table illustrated in FIG. 6, each parameter can take the following values. S (n) can be “1” to “4”. Xs (n) can take “1” to “14”.

  In this example, each sound difficulty level D (n) for the nth sound is the string of the string when moving from the pitch P (n−1) of the immediately preceding adjacent sound to the nth pitch P (n). It is calculated based on the amount of change in type (the amount of movement between strings) and the amount of change in fingering (fingerboard position). The amount of change in the type of string is represented by, for example, | S (n) −S (n−1) |. The amount of change in fingering (fingerboard position) is represented by, for example, | Xp (n) −Xp (n−1) |. Note that the amount of change in the type of string need not be used for calculation of each sound difficulty level D (n).

Specifically, each sound difficulty level D (n) of the violin is calculated by the following equation.
D (n) = {| S (n) -S (n-1) | +1} * | Xs (n) -Xs (n-1) | / 5

  Note that the calculation method of each sound difficulty level D (n) described above is an example, and any method may be used as long as the fingering change amount is used. The above is the description of the calculation method of each sound difficulty level D (n) for each type of musical instrument.

  As described in the evaluation process shown in FIG. 7, the music difficulty level is calculated by accumulating the sound difficulty levels D (n) calculated corresponding to the sounds constituting the music. As described above, the calculation method of each sound difficulty level D (n) differs depending on the type of musical instrument. Therefore, each sound difficulty level D (n) that differs depending on the type of musical instrument is calculated for one sound included in the music. As a result, the degree of difficulty of music varies depending on the type of musical instrument. In particular, the following situations may occur depending on the type of musical instrument.

  For example, in the trombone, when the pitch shifts from “F3” to “E3” (hereinafter referred to as the first transition relationship), when the pitch shifts from “F3” to “C3” (hereinafter referred to as the second transition relationship). There is less change in position than Accordingly, each sound difficulty level D (n) is larger in the second transition relationship than in the first transition relationship. On the other hand, in the alto saxophone, the opening and closing of the key changes greatly in the first transition relationship, although the transition amount of the pitch is smaller than in the second transition relationship. Accordingly, each sound difficulty level D (n) is larger in the first transition relationship than in the second transition relationship.

  That is, when the first transition relation and the second transition relation are compared, depending on the type of musical instrument, the first transition relation has a greater degree of sound difficulty D (n) and the second transition relation. In some cases, each sound difficulty level D (n) is increased. Thus, the music evaluation apparatus 1 according to the present embodiment can calculate the degree of difficulty corresponding to the performance method of the musical instrument for each type of musical instrument even for the same musical composition.
