The light emission control unit 22 includes a music data reading unit 21
Illuminators 4a, 4b, 4c, 4d, 4e of the display unit 3 corresponding to the pitch key 1 indicated by the music data supplied from the
Is controlled. At this point, the light emission control unit 22 includes, in addition to the display unit 3 provided corresponding to the key 1 to be pressed next, the four keys 1 to be pressed sequentially after the key 1 is pressed. Light-emitting members 4a, 4b,
4c, 4d, and 4e are selectively emitted as appropriate. This instructs the player up to five keys to be pressed from that point onward, and also instructs the playing order.

As described above, the light-emitting members 4a, 4b,
4c, 4d and 4e are selectively illuminated, and a luminous element 4 for notifying the player of the keys to be depressed up to five keys and their order.
The light emission control of a, 4b, 4c, 4d, and 4e is shown in FIG.
, The pitches are “G”, “A”, “C”,
An example in which music data flowing in the order of “E”, “C”,... Is used will be described.

First, the luminous state of the luminous bodies 4a, 4b, 4c, 4d, 4e of the display unit 3 at the time when the progress of the music is time t ₁ is as shown in FIG. As shown in FIG.
_{In 1} , all the luminous bodies 4a, 4b, 4c,
4d, 4e, and the luminous bodies 4a, 4b, 4c,
4d, the light-emitting body 4a with the pitch name "G", and the light-emitting bodies 4a and 4b with the pitch name "A" emit light. That is, in this embodiment, at this point, the key 1 to be pressed next is
, Only the light emitter 4a emits light, and as for the display unit 3 corresponding to the second key 1 to be pressed next, the light emitters 4a and 4b emit light. I have. Similarly, for the display unit 3 corresponding to the key 1 to be pressed third, the light emitting bodies 4a, 4b, 4c, 4c
For the display unit 3 corresponding to the key 1 to be depressed first, the light emitters 4a, 4b, 4c, 4d, and the key 1 to be depressed fifth
Are displayed on all the light emitting bodies 4a, 4
b, 4c, 4d, and 4e emit light.
Therefore, the player can select the light-emitting members 4a, 4b, 4
By visually recognizing how many light emitters among c, 4d and 4e emit light, it is possible to know the order in which the keys should be played from that point on.

Here, like the music data used in the present embodiment, the same pitch is pressed a plurality of times out of five pitches to be played after that time, and in this example, the key 1 of "C" is pressed a plurality of times. If necessary, the light-emitting bodies 4a, 4b, 4c, 4d, 4
By properly using the emission color of e, it is possible to inform the player of a plurality of orders. Specifically, FIG.
As shown in FIG. 5, the light-emitting members 4a, 4b, and 4c emit light of a certain color (for example, orange) to indicate that the performance order is third, and emit light to indicate that the performance order is fifth. The bodies 4d and 4e emit light of different colors (for example, green). Thereby, the player can recognize that the keys are the third and fifth keys to be pressed from this point. In FIG. 4, for simplification of description, the light-emitting members 4a, 4b,
Only 4c, 4d, and 4e are described, and the display unit 3 corresponding to the black key is omitted, and the description of the display unit 3 corresponding to the black key is similarly omitted in FIGS. I have.

Next, when the music progresses and reaches time t ₂ ,
The light emission state of the display unit 3 corresponding to each key is as shown in FIG. As shown in the figure, at time t ₂ , the luminous bodies 4 a, 4 b, 4 c, 4 d of the pitch name “C” (the luminous bodies 4 c,
4d and the light emitters 4a and 4b emit light in different colors), the light emitters 4a, 4b and 4c with the note name "E", and the light emitter 4a with the note name "A" emit light. Therefore, after this point, the first key corresponding to "A" 1, the second key corresponding to "C" 1, the third key corresponding to "E" 1, the fourth key corresponding to "C" The player can recognize that the key 1 to be pressed is pressed.

Next, when the music progresses further and reaches time t ₃ , the light emission state of the display unit 3 corresponding to each key becomes as shown in FIG. As shown in the figure, at time t ₃ ,
The luminous bodies 4a, 4b, 4c of the musical name "C" (the luminous body 4c,
The light emitting elements 4a and 4b emit light in a different color), and the sound name "E"
And the luminous bodies 4a and 4b emit light. Therefore, after this point, the player recognizes that the key 1 corresponding to “C” is pressed first, the key 1 corresponding to “E” second, and the key 1 corresponding to “C” third. can do.

Thereafter, the music progresses further, and at time t ₄ ,
When becomes t _5, the light emitting state of the display unit 3 corresponding to the key,
As shown in FIGS. 7 and 8, respectively, the performer
The key to be pressed at each time and the order can be known. Here, during the time t _{1 to} t ₃ , the light emission color is different from the others to notify that the note name “C” is pressed a plurality of times.
As ₄ and time t _5, when the number to be pressed becomes only once, to the emission color may be directly other different emission colors, the same color as the other emission colors It may be returned.

As described above, the light emission control unit 22 shown in FIG. 2 controls each of the light emitters 4a, 4b, 4c, 4d,
By controlling the light emission of 4e, not only the key to be pressed next from that point in time but also the four keys to be pressed after that can be instructed to the player.
The order of playing the two keys can also be specified.

In the above-mentioned example, since the rest after the note name "C" is a rest, the light emission corresponding to the key to be pressed after the note name "C" is not performed. If there is, the light emitters 4a, 4b, 4c, 4d, 4e corresponding to the key of the pitch may be selectively emitted according to the same procedure as described above. Further, even when there is a rest, regardless of the rest, the light emitters 4a, 4b, 4c, 4d, and 4e corresponding to the keys of the pitch after the rest may be appropriately selected to emit light. .

B. Operation of Embodiment Next, the operation of the performance support apparatus having the above configuration will be described. First, a main routine of light emission control by the light emission control unit 22 will be described with reference to FIG.

B-1. Main Routine First, when the power is turned on to this performance support apparatus, an initial state setting process is performed (step Sa1). Here, the initial state setting processing is processing for initializing various registers. Thereafter, it is determined whether the guide mode switch has been operated (step Sa2).

Here, if the guide mode switch is operated, it is determined whether or not the operation has selected the performance support mode (step Sa3). When the performance mode is selected by operating the guide mode switch, 1 is set to the flag A indicating the performance support mode (step Sa4). On the other hand, when the performance support mode is not selected, the flag A is set to 0, and the flag B used in a timer interrupt process described later is set to 0. At this time, all the light emitters of the display unit 3 which are emitting light at that time are turned off (step Sa5).

Thereafter, other necessary processing besides the above processing is executed (step Sa6), and the processing after step Sa2 is repeated.

B-2. Timer Interrupt Processing The main routine of the light emission control unit 22 has been described above. In this performance support device, the timer interruption processing is executed by the light emission control unit 22 at predetermined intervals to execute the light emission control as described above. (See FIGS. 3 to 8). Hereinafter, the timer interrupt processing will be described with reference to FIG.

First, when the timer interrupt process is executed, it is determined whether the flag A is set to 1 (step Sb1). Here, when the flag A is set to 0 instead of 1, that is, when the performance support mode is not selected, the timer interrupt processing ends.

On the other hand, when the flag A is set to 1,
That is, when the performance support mode is selected, it is determined whether or not the flag B is 0 (step Sb).
2). Here, the flag B is a flag for determining whether or not the performance support based on the music data is performed or is being performed. When the flag B is set to 0, it indicates that the performance is not performed. When the flag B is set to 1, it indicates that the program is being executed.

When the flag B is set to 0, that is, before the performance support is executed, the music data reading unit 21 is instructed to read data of the first five notes from the music data, Each of the light-emitting members 4a, 4b, 4
Light emission of c, 4d, 4e is controlled (step Sb
3). Here, the light emission control contents of the light emitters 4a, 4b, 4c, 4d, and 4e are as described above (see FIGS. 3 to 8).

When the data of the first five notes is read out and the display of the display unit 3 is controlled based on this data, the performance support processing is being executed.
Is set to 1 (step Sb4).

Thereafter, at the time when the timer interrupt processing is being performed, whether the key 1 corresponding to the first note in the playing order has been pressed, that is, whether or not the key 1 to be pressed next has been pressed at this time. Is determined (step Sb5). The determination as to whether or not the key is pressed is made based on key press information from the key press sensor 23. In this manner, immediately after the start of the performance support execution, since the key 1 to be pressed next is the first note of the music data, it is determined whether or not the key 1 corresponding to the first note is pressed. You.

Here, when it is determined that the key 1 to be pressed next has been pressed, the music data reading unit 21 is instructed to read one note following the last note currently being read. Then, the light emission control of the display unit 3 corresponding to the note corresponding to the pressed key 1 is stopped, and the display provided on the key 1 corresponding to the newly read note is added to the next four notes. The light emitters 4a, 4b, 4c, 4d, and 4e of the unit 3 emit light so that the performance order is indicated (step Sb).
6). After such light emission control, the timer interrupt processing ends. By repeatedly executing such a timer interrupt process at predetermined intervals, it is possible to sequentially advance musical performance support in response to a key press operation by the player.

In the performance support apparatus according to the present embodiment, when performing performance support, not only the key to be pressed next, but also the four keys to be pressed sequentially after that, together with information indicating the performance order, are performed. Can be notified. Therefore, the player can easily understand the flow of the music based on the notification contents. In addition, since it is possible to know the key to be played to some extent earlier, it is possible to assemble the fingering yourself to some extent, and it is easier to perform a smooth performance. In addition, it becomes easy to understand the appropriate arrangement position of the hand on the keyboard.

Further, in this performance support apparatus, a plurality of light emitters 4a, 4a,
Light emission of 4b, 4c, 4d, and 4e is controlled. As a result, as shown in FIGS. 4 to 8, a plurality of keys to be depressed first and the order of the performance are represented in a bar graph, such as the time until the performance (order) on the vertical axis and the keys to be depressed on the horizontal axis. expressed. Therefore, the player can intuitively be notified of a plurality of keys to be pressed first and the playing order thereof, such that the keys corresponding to the short bar should be pressed sequentially.

C. Modifications The present invention is not limited to the above-described embodiment, and various modifications as described below are possible.

(Modification 1) In the above-described embodiment, if the same key is included a plurality of times among the five keys to be pressed, the key is included a plurality of times by changing the emission color. It is desired to notify the player that the music is being played (note name "C" in FIGS. 4 to 6 and the like), but a method other than changing the emission color may be used. For example,
Blinking light emission may be performed, or light emission intensity may be changed.

(Modification 2) In the above-described embodiment, the musical composition support is advanced in accordance with the player's key depression. However, the musical composition data is indicated instead of the player's key depression operation. The performance support may be advanced according to the progress speed of the music. When performing such a process,
Instead of the timer interrupt process described above, a timer interrupt process as shown in FIG. 11 may be performed.

The timer interrupt processing shown in the figure is executed at intervals corresponding to a predetermined tempo. Here, the cycle corresponding to the predetermined tempo is a cycle determined according to the tempo when the music data includes the tempo information of the music. Can be set, the cycle is determined according to the set tempo. As such a cycle, for example, 4
If a setting such as the length of 1/10 of a minute note is made, the actual time of the cycle is determined according to the set tempo.

When the timer interrupt processing is started,
First, it is determined whether or not the flag A is set to 1 (step Sc1). Here, when the flag A is set to 0 instead of 1, it indicates that the performance support mode is not selected, and the timer interrupt processing ends.

On the other hand, if the flag A is set to 1,
When the performance support mode is selected, it is determined whether or not the flag B is 0, that is, whether the performance support process is before the start or is being executed (step Sc2).
Here, if the flag B is 0 and the performance support processing has not yet started, the music data reading unit 21 is instructed to read data of the first five notes from the music data, and the first read music data is read. The light emission of each of the light emitters 4a, 4b, 4c, 4d, 4e of the display unit 3 is controlled based on the data of five notes (step Sc3). Further, the note length of the read first note is set to the count value D (step Sc).
4). Here, the music data is MIDI (Musical Instrument)
ment digital interface) data, the delta time between the note-on event data and the note-off event data corresponding to the pitch indicated in the note-on event data is set as the count value D. The count value may be set by a value obtained by expressing the note length by a natural number multiple of the above-described period. For example, if the period is set to 1/10 the length of a quarter note as described above, and if the note length is a quarter note, the count value D is set to D = 10. .

When the data of the first five notes is read out and the display of the display unit 3 is controlled based on this data, the performance support processing is being executed.
Is set to 1 (step Sc5).

On the other hand, if the flag B is set to 1,
If the performance support process is being executed, a value obtained by decrementing the current count value D by 1 is set as a new count value (step Sc6). Thereafter, it is determined whether or not the count value is 0 (Step Sc)
7). That is, it is determined whether or not the music has progressed to the next note after the time corresponding to the note length of the first note has elapsed.

Here, if the count value D is not 0, the timer interrupt processing ends. On the other hand, if the count value D is 0 and the time corresponding to the note length of the first note has elapsed until now, the reading of one note subsequent to the last note currently being read is performed by the music data reading unit. 21. Then, the light emission control of the display unit 3 corresponding to the key corresponding to the note that was the first note until now is stopped,
In addition to the next four notes, the light-emitting members 4a, 4b, 4b, and 4b of the display unit 3 corresponding to the key 1 corresponding to the newly read note.
4c, 4d and 4e are illuminated so as to indicate the performance order (step Sc8). After such light emission control, the count value D is set according to the note length that has newly started (step Sc9). Then, the timer interrupt processing ends. By repeatedly executing such a timer interrupt process at the above-described predetermined cycle, it is possible to sequentially advance the music performance support according to the progress speed of the music indicated by the music data.

(Modification 3) As in Modification 2 described above, music performance support may be provided in accordance with the progression speed of music, but in this case, a predetermined time before the music progresses. A key to be pressed may be specified.
In other words, the key to be pressed next or the like may be notified to the performer in advance by a predetermined time before the time to actually play. When performing such a process, a process as shown in FIG. 12 may be performed instead of the above-described timer interrupt process.

The timer interrupt process shown in the figure is also executed at intervals corresponding to a predetermined tempo, similarly to the process of the second modification, and it is first determined whether or not the flag A is set to 1. (Step Sd1). Here, when the flag A is set to 0 instead of 1, it indicates that the performance support mode is not selected, and the timer interrupt processing ends.

On the other hand, if the flag A is set to 1,
If the performance support mode has been selected, it is determined whether or not the flag B is 0, that is, whether the performance support processing has not been started or is being executed (step Sd2).
Here, if the flag B is 0 and the performance support processing has not yet started, the music data reading unit 21 is instructed to read data of the first five notes from the music data, and the first read music data is read. The light emission of each of the light emitters 4a, 4b, 4c, 4d, 4e of the display unit 3 is controlled based on the data of five notes (step Sd3).

When the data of the first five notes is read out and the display of the display unit 3 is controlled based on this data, the performance support processing is being executed.
Is set to 1 (step Sd4).

Thereafter, at the time when this timer interrupt process is being performed, whether the key 1 corresponding to the first note in the performance order has been pressed, ie, whether or not the key 1 to be pressed next has been pressed at this time. Is determined (step Sd5). The determination as to whether or not the key is pressed is made based on key press information from the key press sensor 23.

On the other hand, if the flag B is set to 1,
If the performance support process is being executed, step Sd3
And the processing of step Sd4 is not performed, and step Sd
Proceeding to 5, it is determined whether or not a key is pressed.

Here, when it is determined that the key 1 to be pressed next has been pressed, the flag C indicating whether or not the count value D is decremented is set to 1 (step Sd6), and From the note length to a predetermined length (for example, 8
The count value D obtained by subtracting the note length of the minute note) is set in the counter (step Sd7). The count value D may be set by a value represented by a natural number multiple of the above-described cycle, similarly to the above-described modification 2. When the count value D is set in this manner, the timer interrupt processing ends.

On the other hand, if it is determined in step Sd5 that the key 1 to be pressed next has not been pressed, it is determined whether or not the flag C is 1, that is, whether or not the count value D is to be decremented. (Step Sd8). Here, if the flag C is not 1, the timer interrupt processing ends. On the other hand, if the flag C is set to 1, a value obtained by decrementing the current count value D by 1 is newly set as the count value D (step Sd9). Thereafter, it is determined whether or not the count value is 0 (step Sd10). That is, it is determined whether or not a time corresponding to a length obtained by subtracting a predetermined length from the note length of the first note has elapsed.

Here, if the count value D is not 0, the timer interrupt processing ends. On the other hand, if the count value D is 0, and the time at which the predetermined length has been subtracted from the note length of the note has elapsed after the leading note has been pressed, the flag C is set to 0. At the same time (step Sd11), the reading of one note following the last note currently being read is performed by the music data reading unit 21.
Is instructed. Then, the light emission control of the display unit 3 corresponding to the key corresponding to the leading note up to now is stopped, and the key corresponding to the key 1 corresponding to the newly read note is added to the next four notes. Light-emitting bodies 4a, 4b, 4 of display unit 3
c, 4d, and 4e are illuminated so that the performance order is indicated (step Sd12). After such light emission control, the timer interrupt processing ends. Then, such a timer interrupt process is repeatedly executed at the above-described predetermined cycle, so that the time corresponding to the predetermined length is earlier than the timing of pressing the next key after pressing a certain key. The player can be notified which key to press. Therefore, the performer can know the information about the key to be pressed and the four keys to be sequentially pressed thereafter, and the performance order thereof, a predetermined time before the timing at which the key is actually pressed. .

As described above, in the performance support apparatus, various timings such as the progress of the performance support by the player's key depression described in the above-described embodiment, the progress in accordance with the progress of the music, and the advance notice for a predetermined time are provided. Can perform the performance support processing, but the player may be able to arbitrarily set these three progress modes. Thereby, for example, in the case of a beginner, if a mode in which performance support progresses by pressing a key described in the above embodiment is selected,
It is suppressed that the performance support cannot be followed. On the other hand, for intermediate and higher performers, the progress mode as described in Modifications 2 and 3 may be selected so as to match the progress of the music or to give advance notice. Performance support according to technology becomes possible.

(Modification 4) In the above-described embodiment, in addition to the key to be pressed next, the control for notifying the player of the four keys to be played sequentially thereafter is performed. Not only the key to be pressed next,
Light emission control may be performed so as to notify the performance order of one or more keys, or the performance order may be notified together of three or less keys. The number of light emitters described above may be determined according to the number of keys to be notified.

(Modification 5) In addition, the luminous bodies 4a,
Instead of the display unit 3 composed of 4b, 4c, 4d, and 4e, a monitor such as a liquid crystal display device extending in the vertical direction may be provided. Then, similarly to the above embodiment, the playing order may be indicated by the length in the vertical direction displayed on the liquid crystal display device. Alternatively, the playing order may be simply indicated by a numeral. Also, a light emitting body capable of emitting light in a plurality of colors may be provided corresponding to each key, and the order of performance may be indicated by the light emitting color.

(Modification 6) In addition to the above-mentioned keys to be pressed next, keys to be pressed sequentially thereafter, information on the performance order, and which finger is used to press each key. The fingering information shown may also be notified to the player. In this case, the luminous bodies 4a, 4b,
A method of changing the emission colors of 4c, 4d, and 4e (thumb is red, forefinger is yellow, etc.), or a new display section showing fingering information may be provided for each key.

(Modification 7) In the above-described embodiment, the display section 3 provided for each key 1 is built in the keyboard holding section 2. However, the present invention is not limited to this. May be configured. For example, as shown in FIG. 13, the display unit 3 is built in a box-shaped performance support unit 130 having a length substantially the same as the longitudinal direction of the keyboard,
You may make it detachable to the keyboard cover etc. of a piano.

(Modification 8) In the above-described embodiment, the piano provided with the performance support device has been described.
