Denotes an effect instructing unit, 8 denotes a sound source control unit, 5 denotes a sound source unit, and 6 denotes an external input terminal.

The operation of the automatic performance device configured as described above will be described below.

The sound source control unit 8 sequentially reads coded musical score information in the musical score information memory 1 or musical score information input from the outside, and appropriately changes the timbre effect rhythm effect and the like based on an instruction from the effect instruction unit 9. The tone generator 5 is controlled to generate a musical tone from the tone generator 5 and perform an automatic performance.

Problems to be Solved by the Invention However, in the above configuration, the sound source control unit 8 only has the music score information, and only outputs the sound source information for controlling the sound source unit 5 according to the stored music score information. Only mechanical output corresponding to the score can be obtained without generating new sound source control information from the inside. Alternatively, since the control is performed on hardware, there is a problem that only a simple arrangement performance of a degree in which a tone color effect, a rhythm effect, and the like are changed can be performed. This will be described in more detail below.

Musical scores are written by composers who imagine music and use a language to express music. The performer considers the composer's intentions, the era of the composition, the characteristics of the instrument, and plays with his own interpretation and thoughts, which impresses the listeners.

Therefore, even if the same musical score is played by different people and different instruments, the music that can be heard as a result will be completely different.

For example, it is common knowledge that the music played by a kindergarten child and the music played by a skilled musician have a completely different impression on people, even when playing the piano using the same score.
A wonderful character is read out by speech synthesis using a computer, and a bitter voice actor with many annual rings,
It's like the difference between reading with heartfelt reading.

Play the notes written on the former score without making mistakes. The result is cute when played in front of you, but the music is as dry as a robot played. On the other hand, when a skilled musician performs, the music becomes extremely artistic, which impresses the audience.

The difference is between music played just to make sure that the music is not mistaken, and music played by musicians taking into account the composer's thoughts and their ages, the characteristics of the instruments played, and even the atmosphere of the venue, with the whole body betting on the whole body. Is the difference.

Specifically, the performance is performed by adding fine note information devised by the player as performance information to the note information described in the musical score. The skilled musicians don't have the special sound that kindergarten children don't have.

There is a preset type with a concept similar to automatic performance. In this method, a human comprehend a musical score and arbitrarily record performance information in a system and reproduce it.

In addition, there is a similar device that electronically stores keyboard information played by a human and reproduces it. In addition, some people edit the information to play more artistic music.

These allow a human to add performance information over the entire music score and memorize a music score with detailed performance information in a machine. Therefore, trying to play music with a different image using the same original music score required a complete re-creation.

Is to do so.

For example, if the performance information of a skilled musician is analyzed while collating it with the original music score, and the rules for performance extracted therefrom are stored in the device as conversion rules, the composer, the age and category of the music, etc. Based on the above, according to the entire structure and the partial structure of the score, etc., a conversion rule for converting the score into a detailed score for playing it is analyzed and extracted.

By applying these conversion rules to the score,
Create detailed performance information corresponding to the score. Of course,
This conversion rule is effective when applied to another musical score belonging to the same music genre (composer, period, musical composition, etc.).

Applying the conversion rules extracted from different musicians to the same score will produce different performance effects.

By inputting the performance information obtained as a result to another sound source section, music with high musicality is played, and people are impressed.

By replacing this conversion rule with another conversion rule (containing a plurality of rule groups), learning sequentially, and adding a special conversion rule by the user, more advanced music performance will be realized. Things.
