With such electronic musical instruments, it is possible to efficiently practice playing by referring to model performances, but it is difficult for practitioners to objectively analyze their own performances and improve their practice efficiency by using tapes. This was inconvenient as the only option was to use auxiliary means such as a recorder.

The purpose of this invention was to record and record data based on actual performances.
The purpose is to provide a musical score sheet that can be played.

The musical score sheet according to this invention is characterized in that the sheet body is provided with a data recording section for manual performance in addition to a data recording section for automatic performance, so that the performance data of the practitioner can be recorded and played back as appropriate. Embodiments shown in the accompanying drawings will be described in detail below.

FIG. 1 shows a musical score sheet according to an embodiment of this invention.

The musical score sheet 10 has a sheet main body made of paper or plastic that is hard enough to stand upright, and a musical piece written on the surface (front side) of the sheet main body in accordance with musical notation (usually using a staff notation, a string of notes, etc.). The song description section,
The sheet includes first and second data recording sections 10a and 10b provided near the lower end of the front side of the sheet body.

For example, the data recording sections 10a and 10b are composed of separate magnetic tapes, but they may also be composed of a single magnetic tape having multiple tracks.

Note that the recording/reproducing method is not limited to a magnetic method, but may be an optical method using a bar code or the like.

Furthermore, the installation positions of the data recording units 10a and 10b are preferably arranged as shown in Fig. 1, since recording and playback can be performed with the music sheet standing upright on the music stand. Alternatively, if special measures are taken to the recording/reproducing device, the recording/reproducing device may be placed near another end of the front side of the sheet body, or on the back side of the sheet body.

The first data recording section 10a records automatic performance data (data such as pitch, note length, timbre, effect, etc.) corresponding to the content of the musical score, but the second data recording section 10b usually does not contain any data. is also not recorded.

That is, the second data recording section 10b is intended to record data based on manual performance during performance practice.

FIG. 2 shows an example of an electronic musical instrument as an apparatus for using the musical score sheet.

When the write command switch 12 is turned on with the sheet music sheet 10 standing on the music stand, the playback device 14, the write circuit 16, and the RAM (random access memory) are activated.
The data memory 18 consisting of the following is enabled in response to the write command signal PL.

Therefore, the automatic performance data in the first recording section lea is read by the playback device 14 and written into the data memory 18 by the write circuit 16.

Next, when the sound generation select switch 20 is turned on, the on signal is passed through the OR gate 22 to enable the readout control circuit 24, and also enables the tone forming circuit 26.

Therefore, the read control circuit 24 sequentially reads automatic performance data from the data memory 18 and supplies it to the musical tone forming circuit 26, and the musical tone forming circuit 26 sequentially forms musical tone signals in accordance with the supplied data.

The musical tone signal from the musical tone forming circuit 26 is supplied to the speaker 30 via the output amplifier 28, and an automatic performance sound is produced from the speaker 30.

On the other hand, when the display select switch 32 is turned on without turning on the sound generation select switch 20, the on signal goes through the OR gate 22 to enable the readout control circuit 24, and also enables the key press display control circuit 34. do.

Therefore, the readout control circuit 24 sequentially reads out the automatic performance data from the data memory 18 and displays it in the key press display control circuit 34.
The key press display control circuit 34 selectively lights up the display elements provided for each key of the keyboard 36 in accordance with the supplied data to display the key to be pressed.

If the sound generation selection switch 20 is turned on together with the display selection switch 32, the automatic performance sound generation and automatic key press display operations described above are performed in parallel.

Performance data based on manual performance on the keyboard 36 is supplied to a musical tone forming circuit 38 and converted into a musical tone signal.

The musical tone signal from the musical tone forming circuit 38 is supplied to the speaker 30 via the output amplifier 28, and the manual performance sound is also produced from the speaker 30.

According to the above configuration, the practitioner can efficiently practice performance while listening to the automatic performance sound and/or viewing the automatic key press display.

During such performance practice, manual performance data can be stored or recorded as described below, and the stored or recorded data can be read out at an appropriate time after the manual performance is completed to reproduce one's own performance. , can be analyzed and used to improve playing techniques.

To store manual performance data, the write command switch 40 is turned on.

The ON signal of this switch 40 enables the write circuit 42 and also puts the data memory 44 consisting of RAM into the write mode, so that the manual M data from the keyboard 36 is sequentially transferred to the data memory 44 by the write circuit 42. written.

After such writing, when the sound generation select switch 46 is turned on, the on signal enables the readout control circuit 48 and the tone forming circuit 50.

Therefore, the read control circuit 48 sequentially reads manual performance data from the data memory 44 and supplies it to the musical tone forming circuit 50, and the musical tone forming circuit 50 sequentially forms musical tone signals in accordance with the supplied data.

The musical tone signal from the musical tone forming circuit 50 is supplied to the speaker 30 via the output amplifier 28, and the speaker 30 produces a performance based on the stored manual performance data.

On the other hand, in order to record manual performance data on the musical score sheet 10, the recording command switch 52 is turned on after writing to the memory 44.

The recording command signal REC from this switch 52 is transmitted to the memory 4.
4 and the read/write circuit 54 are set to the read mode, and the recording/reproducing device 56 is set to the recording mode, so that the memory 44
The manual performance data is sequentially read out by the read/write circuit 54 and supplied to the recording/reproducing device 56, and the recording/reproducing device 56 magnetically records the supplied data sequentially in the second data recording section 10b. .

Thereafter, to read the recorded data, the reproduction command switch 58 is turned on.

The playback command signal PL2 from this switch 58 puts the recording/playback device 56 into playback mode and the read/write circuit 5
