By pressing in the order of the display, the fingering lesson about the lesson music can be taught.

A program for fingering display processing will be described below with reference to FIGS. 2 and 4.

This program is executed by the CPU 207 when the power is turned on in the fingering display control unit 203. First, the memory such as the RAM 209 is cleared, the LED is extinguished, the timer flag is reset, the timer is reset, and the like for initialization (S1). Next, the number of the musical piece of the ensemble is displayed on the numeric keypad 24 from the operation unit 213.
It is input by 0 (S2). That is, this input signal is transmitted from the operation unit 213 to the I / O unit 204. Then, the CPU 207 transmits the song number to the input / output unit 250 of the MIDI device (sequencer) 212 (S
3). As a result, the sequencer 212 reads the data of the music piece from the FD 252 of the floppy disk device 251 according to this music piece number. After the output to the sequencer 212, the CPU 207 stands by until the start switch 241 of the operation unit 213 is turned on (S4).

When the start switch 241 is turned on, the CPU 207 sends a start signal to the sequencer 212 (S5). As a result, the sequencer 212 uses the tone generator 253 as a sound source to generate the tone signals of the musical instrument parts other than the piano part according to the data of the ensemble song selected by the song number.
Output to 2 and start playing the musical sound of that part. At the same time, regarding the piano part of the ensemble song,
Key-on signal (note ON), key-off signal (note O
FF), note numbers included in these. The sequencer 212 transmits musical performance data such as "" to the fingering display control unit 203 in the order of progression of the music. For example, after a note-on signal for one musical tone is input, a note-off signal for that musical tone is input after a predetermined time. And this note-on signal, note-off
The signals are input in the order of progression of a series of musical tones that make up the piano part. Until there is an input from the sequencer 212, the CPU 207 keeps the stop switch 24
The ON operation of No. 2 and the end of the music are checked (S6), and there is an ON operation, or the performance of the music ends (for example, in the performance data transferred from the sequencer 212, data indicating the end of the music. Is received), the process returns to step S1 (S6).

Next, when the stop switch 242 is not ON and the music is not completed (when the determination in S6 is NO), the CPU 207 outputs from the sequencer 212 a note ON signal of the piano part of the ensemble music. It is checked whether it has been input (S7). When the note-on signal is input (YES in S7), the CPU 207 determines that the note-no. LED is turned on according to
8). As a result, the note No. Key 11 or 12
The corresponding portion of the display unit 202 is lit and displayed corresponding to. This display clearly shows the key 11 or 12 to be tapped to the trainee.

Specifically, when performance information (digital data) for the ensemble is input from the sequencer 212, the CPU 207 outputs an LED lighting control signal to the LED drive circuit 204a based on the input MIDI signal. .. This LED lighting control signal is the note number of the piano part. Is for turning on the LED 204b corresponding to. As a result, the LED 204b is turned on at a predetermined timing, and the optical fiber cable 20
The display unit 202 according to the lighting state via 2b.
Is displayed by light emission.

Next, from the input of the note ON signal to the note O
Until the input of the FF signal, the keystroke signal (detected by the key sensor 103) of the key 11 or 12 which is lit and displayed is I /
It is determined whether or not the data is input to the O unit 204 (S
9). When not input, the process proceeds to step S12,
When the note OFF signal is received after that, the LED turn-off control signal is sent to the LED drive circuit 204a.
(S10). In response to the keystroke display, it is determined that the keystroke has been correctly made, and the LED 204b that has been turned on is turned off. Then, the light emitting point near the corresponding key 11 or 12 of the display unit 202 is also turned off. further,
The timer flag FT indicating that the timer 206 is measuring time is reset, and the process returns to step S6 (S11). Thereafter, the lighting display for keystroke is displayed based on the note-on signals continuously input, and this display is repeatedly turned off by the keystroke detection. As a result, the learner can practice practicing keystrokes while listening to the musical sounds of the parts other than the piano while visually observing the keys 11 or 12 of the piano part displayed simultaneously with the generation of the musical sounds.

Next, at step S12 (when the key is not pressed despite the lighting), it is judged whether or not the timer flag FT indicating the time measurement of the timer 206 is set (whether or not the time is being measured) to measure the time. If it is medium, the process proceeds to step S15.
If it is not timed (NO in S12), the timer 206 that starts timed for a predetermined time to allow a keystroke error is activated (S13), and the timer flag FT is set (S1).
4).

Next, the CPU 207 determines that the measured value T of the timer 206 is a predetermined time T0, for example, 1
It is determined whether the time exceeds 0 seconds (S15). If not, the process returns to step S6 and the note No. of the next note ON signal is input. The LED 204b is turned on in response to this. In this way, S6, S7, S8, S9, S12, and S15 are repeatedly executed, and the display unit 20 simultaneously displays a plurality of keys 11 or 12 (for example, one bar) within a predetermined time.
2 will be displayed. For example, within a predetermined time T0,
When the latest keystroke displayed and the actual keystroke match, other keys extinguish except the note-on key (key to which no note-off signal is input) at that time, and the speaker system 502 You may make it continue playing the music of.

The measured value T of the timer 206 is the predetermined time T
If it exceeds 0 (YES in S15), it means that correct keystrokes have not been made even after the lapse of the predetermined time (10 seconds). Therefore, the sequencer 212 is instructed to stop the generation of the musical sound from the speaker system 502. Output (S1
6). At the same time when the generation of this musical sound is stopped, the sequencer 212
The transfer of performance data from the to the fingering control unit 203 is also stopped. That is, if the latest key pressed and displayed within the predetermined time does not match the actual key pressed, the music reproduction from the speaker system 502 is temporarily stopped, and only the key pressed display continues to be displayed.

Further, it is judged whether the stop switch is ON or the end of the tune (S17). When the stop is made by these, the process returns to step S1. Stop switch 242 is OFF
And if the song has not ended (S17: N
O), the generation of the musical sound is stopped and the apparatus stands by until any one of the keys 11 or 12 among the plurality of keystroke indicators that are turned on during the predetermined time is tapped (S18).

Next, the CPU 207 makes the displayed key 11
Or if any one of 12 is pressed (Y in S18
(ES), all the LEDs 204b displayed by keystroke are turned off (S19). Then, the restart instruction for the generation of the musical sound from the speaker system 502 and the restart instruction for the transmission of the data of the performance of the piano part to the fingering control unit 203 are output to the sequencer 212, and the process returns to step S6 (S20). .. As a result, for example, the tone generation is restarted from the next bar after the display, and the note No. of the note-on signal transferred in synchronization with this is generated. The display unit 202 is lit and displayed corresponding to (S8). If the displayed key 11 or 12 is not pressed, the plurality of keys 11 or 12 are lit up for a predetermined time T0 (S15). Then, the generation of the musical sound is stopped and the key waiting is waited.

In the present embodiment, since the music proceeds by generating musical sounds other than the piano, even a player at the beginning can enjoy the ensemble performance by playing only a simple melody part. You can also learn advanced ensemble performances such as piano concertos as your performance skills improve.
In addition, the LED unit 204b is built in the fingering display control unit 203, and the optical fiber cable 202
Since it is configured to be transmitted to the display unit 202 by b, the display unit can be made thin and lightweight.
