Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a performance navigation device for self-studying performance techniques. [Conventional technology]

Conventionally, as shown in Japanese Patent Publication No. 60-46432, a device for assisting self-study of musical performance techniques on a keyboard instrument has been used to display the position of a key pressed as the music progresses and which finger is used to press the key at that position. Some devices teach or guide which keys should be pressed using hand-shaped fingering instruction means.

[Problem to be solved by the invention]

However, since the above device simply instructs the next key position and which finger to use, as the song progresses, the range of the next key position may be far different from the range of the current key position. In this case, the user hastily moves his/her hand to the next key press position, which may lead to a mistake in one operation, which is not sufficient for correct self-study of performance techniques. The technical objective of the present invention is to solve the above-mentioned problems, and it enables smooth fingering when teaching oneself the playing technique of a desired piece of music, and makes it possible to learn the correct playing technique by oneself. The purpose of the present invention is to provide a performance navigation device that can perform the following tasks. [Means for Solving the Problems] The present invention is applied to a keyboard instrument having a plurality of keys, a string instrument having a plurality of frets, and the like. Therefore, in order to solve the above-mentioned technical problem, the present invention provides a performance control to be operated next (or a performance control position W) to be operated next according to the progress of a desired piece of music from among a plurality of performance controls (or performance control positions W). A first instruction means for sequentially instructing the position of the player's arm or a position of a part related thereto is provided. Here, the above-mentioned "parts related to the arm" move at the same time as the arm moves. Refers to parts such as the ring finger, the back of the hand, and the wrist.

[Effect]

In the above configuration, as the desired musical piece progresses, first, the position of the performer's arm or the position M (
For example, the ring finger, back of the hand, wrist, etc.) are indicated. Thereafter, the performance operator (or performance operation position) to be operated first is designated. As a result, even if the performance controller (or performance operation position) to be operated next is far away from the current performance controller (or performance operation position), the next performance operation will be performed according to the instructions from the second instruction means. By positioning the arm or related parts in advance at the position of the performance control (or performance operation position) to be used, the performance control (or performance operation position) can be operated smoothly. This will prevent erroneous operations. As a result, it becomes possible to acquire performance techniques correctly, and it is possible to rapidly improve the performance operation of a desired piece of music.

For example, in the example of the music shown in FIG. 2, if key 1-4 corresponds to pitch data KN=64, the light emitting diode 26-4 corresponding to key 1-4 is lit in green. Next, arm position tone length data APL (=48) is set in the first timer Tl in the timer 12, and the data APL
After a period of time has elapsed, an interrupt request from the interrupter is generated from the timer Tl, and the processing from step 100 onward is executed again. Thereafter, when a time equivalent to the APL time has elapsed and an interrupt request from the interrupter is generated from timer T1, the CPU 4 performs the operations from step 100 onwards, and obtains the next arm position data AP.

The light emitting diode 26-4 corresponding to is lit in green,
Next, between the first E note and the next G note, the light-emitting diode at the key position corresponding to the center note of the C, E, and quarter rest groups one octave higher is lit green. Ru. In this way, each time a time period in which operation can be performed with the same arm position has elapsed, and before a key press operation is started at the next arm position, the arm position where the next key press operation will be performed is determined in advance by the light emitting diode 26.

, among the fingering information TF regarding which finger to press the key, data regarding the first note C is read from the memory area M1 of the ROM 5 (step 200). After this, Information KON II
KOF is instructed to start sounding at 0117.
Step 201). If the start of sound generation is instructed, pitch data KN (second The byte b2) is read out and the key light emitting diodes 26-1 to 26- corresponding to the pitch data KN are read out.
○ lights up in red (steps 202, 203). For example, in the example of the music shown in FIG. 2, for the first C note, the light emitting diode 26-1 corresponding to 1l11-1 is lit in red. Next, read the tone length data LD of the third byte b3,
Set the tone length data LD to the second T2 of the timer 12,
After the data LD time has elapsed, an interrupt request for interrupt 2 is generated from timer T2, and the processing from step 200 onward is executed again (step 2o4). Next, read the fingering data TF of the fourth byte b4,
The light emitting diode 20 at the finger position corresponding to the data TF

701 II, it is instructed to press with the thumb. After that, when a time equivalent to the LD time has elapsed and an interrupt request for interrupt 2 is generated from timer T2, the CPU 4 performs the operations from step 200 onwards, and moves on to reading the data at the next key press position. is data related to key release, the first byte of which is KOF="00", instructing to stop sound generation. Therefore, when the first byte b1 instructs to stop sound generation, that is, when KOF="00", the CPU 4 reads the pitch data KN of the key to be released from the next byte b2, and reads the pitch data KN of the key to be released from the next byte b2. The display of the key press position indicated by the red lighting of the light emitting diode of the key corresponding to the key is turned off, and the fingering display of the fingering display section 25 is also turned off (steps 208 and 209). After that, the CPU 4 performs step 20.
Perform the operations from 2 onwards, and set the data KON at the next key press position to 0.

Light emitting diode 26- at the key position corresponding to the data KN
E to 26-n are turned on to emit red light. Therefore, in the musical example in Figure 2, the first C note $
When key 1-1 is pressed, the light emitting diode 26-e corresponding to key 1-1 of this C light is lit in red *1-
1 is instructed to press, and at the same time the fingering display section 25
The zero light emitting diode 20 indicates that the C note should be pressed with the thumb. While the CPU 4 instructs the fingering, key press position, and arm position as described above, the CPU 4 also uses the pitch data KN of the key press position read from the memory M1 and the data KON indicating the start of sound generation.
is transferred to the tone generating circuit 7 in synchronization with the read timing. Then, the musical sound generation circuit 7 generates musical waveform data of a pitch corresponding to the input pitch data KN, and further generates KON as timing data for the musical sound waveform data.
After performing amplitude control using an envelope waveform generated in synchronization with , the signal is input to the DA converter 8 . The DA converter 8 converts the inputted musical waveform data into an analog musical tone signal with a corresponding amplitude level, and after amplifying the signal in an amplifier 9, the signal is produced as a musical tone from the speaker 10. Therefore, those who wish to self-study songs should use ROM5
Regarding musical tones, which can be called simulated performances, that are automatically played using pitch data KN stored in advance, key press positions,
