1) If not turned on, this flow ends. When this switch is turned on, the start flag STF is inverted (step B2). Then, it is determined whether or not the STF has changed from "0" to "1" (step B
3). When STF changes to "1", it means that the start of the automatic performance is instructed. Therefore, the address register AD
The start address is stored in (step B4). Next, the event data of the music ROM (AD) designated by AD is stored in the register NOTE (step B5). That is, since the event data at the start address of the music ROM is key pressing data, the key number is stored in NOTE. Next, the address of AD is incremented (step B6), and the key number indicating the hand position of the song ROM (AD) designated by AD is stored in the register HAND (step B7). Next, the LEDA of the key having the key number stored in NOTE is turned on (step B8). That is, the LEDA of the key to be pressed at present is turned on to guide the performance. When the STF changes from "1" to "0" in step B3, it is a case where an instruction to stop the automatic performance is given, and therefore all the LEDs are turned off (step B9). After turning on the LEDA in step B8 or turning off all the LEDs in step B9, the process returns to the main flow.

FIG. 5 shows step A in the main flow.
It is a keyboard processing flow of No. 3. In this flow, the key is scanned (step C1) and it is determined whether or not there is a key change (step C2). If there is no key change, this flow ends. When there is a key change from off to on, that is, when a key is pressed, the key number of the key is pressed in the register K.
Store in EYON (step C3). Then, a note-on event is created (step C4). In step C2, when there is a key change from on to off,
That is, when the key is released, the key number of the key release is stored in the register KEYOFF (step C5). And
A note-off event is created (step C6). After this, the note-on event created in step C4 or the note-off event created in step C6 is sent to the sound source unit 9 (step C7). And

If it is, it is determined whether the NOTE key number and the KEYON key number match (step D2).
If the key numbers do not match, or if STF is "0" in step D1, this flow ends. When the key numbers match, that is, when a key whose LEDA or LEDB is lit as a key to be pressed is pressed, the lit LEDA or LEDB is turned off (step D3). Next, the address of AD is incremented (step D4) and it is determined whether or not the song ROM (AD) is END data (step D).
5). If it is event data instead of END data, the key number of the song ROM (AD) is registered in the register NEXT.
Store in NOTE (step D6). Furthermore, AD
Is incremented (step D7), and the key number corresponding to the hand position of the music ROM (AD) is stored in the register NEXTTHAND (step D8).

Next, it is determined whether or not the key number stored in NEXTTHAND is within the range of the value obtained by subtracting "2" from the key number of HAND and the value obtained by adding "2" to the key number of HAND. (Step D9). That is, HAND
It is determined whether or not there is a key to be pressed next within the range of 5 keys centered on the key number of. In the example of FIG. 7, it is determined whether or not there is a key to be pressed next within the range of the hand width divided by the two dotted lines 18. As a result of this determination, NEXTHAN
If the key number stored in D is within the width of the hand, the LEDB corresponding to this key number is turned on (step D10). On the other hand, when the key number stored in NEXTTHAND is not within the range of the hand width, the LEDA corresponding to this key number is turned on (step D11).

In FIG. 7, the LED of the key that should be currently depressed.
When a key is pressed as shown in FIG. 8 in a state where A19 is lit, LEDA of the three keys is hidden by the index finger, the middle finger, and the little finger. Further, as shown in FIG. 9, when the position of the hand is further back, the LEDA of the leftmost key is hidden by the thumb. That is,
When the key to be pressed next is guided while the key to be pressed currently is being pressed, if the LEDA of the key is within the range shown by the dotted line 18, then the player's hand 15 will press the key next. The LEDA of the key to be locked may be hidden. In this case, as shown in FIG. 8, the LEDB 20 on the inner side of the key,
21 is turned on. On the other hand, when the LEDA of the key to be pressed next is not within the range of the dotted line 18, as shown in FIG.
The LEDs A22, 23 on the front side of the key are turned on. In addition, there are a plurality of keys to be pressed next, and their LEDA are indicated by the dotted line 18
10 and the case not within the range of the dotted line 18 are mixed, as shown in FIG.
LEDA2 on the front side of the key while lighting the DB24
Turn on 5. Furthermore, when playing with both hands, LEDA
When there is a case where is within the range of the dotted line 18 and a case where is not within the range of the dotted line 18, as shown in FIG. 11, the LEDs B26, 27, 28 on the back side of the key are turned on, and
The LED A29 on the front side of the key is turned on. Similarly, when the next key to be pressed is the black key, the LEDA is also indicated by the dotted line 18
It is discriminated whether or not it is within the range and the LEDB or LEDA is turned on according to the discrimination result. If the key to be pressed currently or the key to be pressed next is a black key, the NEXTNOTE determination range in step D9 may be set differently from that of the white key.

After the LEDB is turned on in step D10 of FIG. 6 or the LEDA is turned on in step D11, the key number of NEXTNOTE is stored in NOTE (step D12), and the key number which is the hand position of NEXTTHAND is set. Store in HAND (step D1
3). That is, the key number of the key to be pressed next and the key number of the hand position are stored in the corresponding registers NOTE and HAND as the key number of the key to be currently pressed and the key number of the hand position. . Then, the process returns to the main flow. At step D5, the song ROM (AD) is END
If it is data, STF is returned to "0" (step D14), and all the LED groups are turned off (step D1).
5). Then, the process returns to the main flow.

As described above, in the first embodiment, it is determined whether or not the LEDA of the key to be pressed next is within the width of the hand for operating the key to be pressed currently. ,
If there is no LEDA within that range, the LED
LED of the key that should be pressed next within the range
When A is present, the LED B of the key to be pressed next is caused to emit light. Therefore, when guiding a key to be pressed, the player can easily recognize the key to be played next, regardless of the position of the hand playing the key to be currently played.

Next, a second embodiment of the musical performance training apparatus according to the present invention will be described with reference to FIGS. In the second embodiment, the internal configuration of the electronic keyboard instrument used as an example of the performance training apparatus is basically the same as the configuration of the electronic keyboard instrument of the first embodiment shown in FIG. Therefore,
A second embodiment will be described with reference to the electronic keyboard instrument shown in FIG. However, the music data of the performance lesson music of the music ROM 6 in the second embodiment is composed of only the key numbers as shown in FIG. 12, and does not include the key number indicating the position of the hand.
In addition, the switch unit 5 in the second embodiment is provided with a setting switch that allows the player to set the hand width. Next, the operation of the performance training processing in the second embodiment will be described. FIG. 13 is a main flowchart of the CPU 1 in the second embodiment. In this flow,
After a predetermined initialization process (step A1), a start / stop switch process (step A) for detecting ON / OFF of the start / stop switch of the switch unit 5 is performed.
2), a width setting process for setting the width of a key pressing hand (step A3), a keyboard process for searching for changes in the keyboard 7 (step A4), and a light emission process for controlling emission and extinction of the LED group 8 of the keyboard 7. (Step A5), other processing (Step A
A loop process for repeatedly executing 6) is performed.

FIG. 14 is a flow chart of the start / stop switch process of step A2 in the main flow. It is determined whether or not this switch is turned on (step B1), and if it is not turned on, this flow is ended.
When this switch is turned on, the start flag ST
F is inverted (step B2). Then, it is determined whether or not the STF has changed from "0" to "1" (step B3). When the STF changes to "1", the start of the automatic performance is instructed, so the start address is stored in the address register AD (step B).
4). Next, the key number of the song ROM (AD) designated by AD is stored in the register NOTE (step B5). Also, the song ROM (A specified by the next address (AD + 1)
The key number of (D + 1) is stored in the register NEXTNOTE (step B6). Next, the LED A of the key having the key number stored in NOTE is turned on (step B7). That is, the LEDA on the performance side of the key to be pressed at present is turned on to guide the performance. When the STF changes from "1" to "0" in step B3, it is a case where an instruction to stop the automatic performance is given, and therefore all the LEDs are turned off (step B8). After turning on the LEDA in step B7 or turning off all the LEDs in step B8, the process returns to the main flow.

FIG. 15 is a flow of the width setting process of step A3 in the main flow of FIG. It is determined whether or not the hand width setting switch is turned on (step C
1) If this switch is not turned on, this flow is ended, but when this switch is turned on, it is judged whether or not the data for the hand width is input (step C).
2). This data is input as the number of keys on the keyboard, that is, the pitch difference. When the data is input, the data is stored in the register WIDTH (step C3). That is, the performer sets the number of keys corresponding to the width of his hand. After storing the data, it is determined whether or not the end switch is turned on (step C4). If the switch is not turned on, the process proceeds to step C2 to wait for data input. When the end switch is turned on, this flow is ended and the process returns to the main flow.

FIG. 16 is a keyboard processing flow of step A4 in the main flow of FIG. In this flow, the key is scanned (step D1) and it is determined whether or not there is a key change (step D2). If there is no key change, this flow ends. When there is a key change from off to on, that is, when a key is pressed, the key number of the key is stored in the register KEYON (step D3). Next, create a note-on event (step D4),
It is sent to the sound source unit 9 (step D5).

In the second embodiment, as shown in FIG. 12, the music data does not include data indicating the position of the hand. Therefore, when a key is pressed, it cannot be recognized in advance whether or not the LEDA that is lit to guide the key to be pressed next is hidden by the hand. Therefore, the next key to be pressed is NEXTNO.
Note that the TE key number is the range of the width of the hand while pressing the key.
It is determined whether it is between -WIDTH / 2 and NOTE + WIDTH / 2 (step D6). NEXT
If the NOTE key number is within this range, the LED
It is determined whether A (NEXTNOTE) is lit (step D7), and if it is lit, the LED
Turn off A (NEXTNOTE) and turn on LEDB (NEXT)
TNOTE) is turned on (step D8). Then, the process returns to the main flow.

When there is a key change from on to off in step D2, that is, when the key is released, the key number of the key release is stored in the register KEYOFF (step D9). Then, a note-off event is created (step D10) and sent to the sound source unit 9 (step D11). Since the target to guide the performance is a beginner, the hands are often released from the keyboard after the key is released. Therefore, after the key is released, it is determined whether or not any of the LEDs B is lit (step D12). If there is an LEDB that is lit, all the LEDsA become visible when the key is released, so that LEDB is turned off and the LEDA provided for the same key is turned on instead (step D13). Then, the process returns to the main flow.

FIG. 17 is a flow chart of the light emission process of step A5 in the main flow of FIG. First, STF
Is determined to be "1" (step E1), and ST
If F is "1", the NOTE key number and KEY
It is determined whether or not the key number of N matches (step E2). If the key numbers do not match, or if STF is "0" in step E1, this flow ends. When the key numbers match, that is, when a key whose LEDA or LEDB is lit as a key to be pressed is pressed, the lit LED is turned off (step E3). Next, the address of AD is incremented (step E4), and the song ROM (AD) becomes EN.
It is determined whether or not it is D data (step E5). E
If the key number is not the ND data, the key number is stored in the register NEXTNOTE (step E).
6).

Next, the key number stored in NEXTNOTE is the NOTE-WIDT which is the range of the width of the hand during key depression.
It is determined whether or not it is within the range from H / 2 to NOTE + WIDTH / 2 (step E7). NEXTNOT
If the key number of E is within this range, LEDB (N
EXTNOTE) is turned on (step E8). on the other hand,
If the key number stored in NEXTNOTE is not within this range, LEDA (NEXTNOTE) is turned on (step E9). After turning on LEDB or LEDA, the key number of NEXTNOTE is stored in NOTE (step E10), and the key to be pressed next is guided. Then, the process returns to the main flow. In step E5, when the song ROM (AD) is END data,
STF is returned to "0" (step E11), and all the LEDs are turned off (step E12). Then, the process returns to the main flow.

As described above, in the second embodiment, the range of the width of the hand to be depressed is set in advance, and the key should be depressed next within the range of the width of the hand to operate the key to be depressed at present. It is determined whether or not the key LEDA exists, and when the LEDA does not exist within the range, the LEDA is caused to emit light, and when the key LEDA to be pressed next exists within the range. , LEDB of the key to be pressed next is caused to emit light. Therefore, as in the case of the first embodiment, when guiding the key to be pressed, even if the LEDA of the key to be pressed next is covered by the hand playing the key to be currently played, The player can easily recognize the key to be played next.
Also, by setting the range of the width of the key to be depressed according to the setting, it is possible to provide a performance guide flexibly corresponding to any performer, from children with small hands to adults with large hands.

Next, a third embodiment of the musical performance training apparatus according to the present invention will be described with reference to FIGS. In the third embodiment, the internal configuration of the electronic keyboard instrument used as an example of the performance training device is basically the same as the configuration of the first embodiment shown in FIG. Therefore, also in the third embodiment, the operation of the performance training process will be described with the aid of the electronic keyboard instrument shown in FIG. However, the music data of the performance lesson music of the music ROM 6 in the third embodiment is composed of key numbers and performance symbols as shown in FIG. Performance symbols include staccato and legato. FIG. 19 shows
The position of the finger 31 that touches the key 30 to be pressed according to the performance symbol, and the LEDA 32 and LEDB embedded in the key 30
It is a figure which shows the position of 33.

The staccato is a method of playing by clearly separating the sounds. Therefore, as shown in FIG.
The pressed finger 31 is on the front side of the LEDA 32. On the other hand, in the case of normal performance, as shown in FIG. 19 (2), the depressed finger 31 is on the back side of the LEDA 32.
Legato is a method of playing without letting you feel a break in the sound. Therefore, as shown in FIG. 19C, the pressed finger 31 is located farther back than the LEDA 32. That is, the position of the finger to be depressed changes according to the performance symbol. Therefore, in the third embodiment, the light emission of the LED is controlled according to the performance symbol of the music data.

As the main flow of the CPU 1 in the third embodiment, either the main flow of the first embodiment shown in FIG. 3 or the main flow of the second embodiment shown in FIG. 13 can be applied. Therefore, a characteristic operation of the performance training processing in the third embodiment will be described here. FIG. 20 is a flow chart of the light emission process in the third embodiment. First, it is determined whether or not STF is "1" (step F1), and if STF is "1", NO.
It is determined whether the TE key number and the KEYON key number match (step F2). If the key numbers do not match, or if STF is "0" in step F1, this flow ends. When the key numbers match, that is, when a key whose LEDA or LEDB is lit as a key to be pressed is pressed, the lit LEDA or LEDB is turned off (step F3). Next, the address of AD is incremented (step F4) and it is determined whether or not the song ROM (AD) is END data (step F5). If the key number is not the END data, the key number is set in the register NEX.
