Claims

A device for generating fingering information indicating fingering when carrying a musical piece by operating a group of performance operators provided in a musical instrument,
Performance information acquisition means for acquiring performance information indicating the performance content of the music;
With reference to the performance information acquired by the performance information acquisition means, fingering information generation means for generating fingering information of the music whose performance information indicates the performance content;
Search means for searching for fingering information corresponding to a fingering that satisfies a predetermined condition among the fingerings indicated by the fingering information generated by the fingering information generating means;
Of the fingering information generated by the fingering information generating means, difficulty calculating means for calculating the difficulty in performing the fingering indicated by the fingering information excluding the fingering information searched by the searching means; ,
Fingering information correction means for correcting the fingering information generated by the fingering information generation means based on the difficulty level calculated by the difficulty level calculation means;
A fingering information generation device comprising:

The difficulty level calculation means virtually divides the performance information into one or more partial performance information with reference to the performance information, and includes the performance content represented by the partial performance information and the connection of the partial performance information. Calculating the degree of difficulty by focusing on at least one of
The fingering information generation device according to claim 1.

The performance content represented by the partial performance information includes at least one of a difference in sound generation start timing between the sounds to be generated, the number of sounds to be generated at the same time, a ratio of overlapping sound generation periods between the sounds, and presence / absence of jumping progress. Focus on the
The fingering information generation device according to claim 1 .

A program to be executed by a computer used as a fingering information generating device that generates fingering information indicating fingering when a musical piece is operated by operating a group of performance operators provided in a musical instrument Because
A function of acquiring performance information indicating the performance content of the music;
A function for generating fingering information of a music piece that indicates the performance content with reference to the performance information acquired by the function to be acquired;
A search function for searching for fingering information corresponding to a fingering that satisfies a predetermined condition among the fingerings indicated by the fingering information generated by the generating function;
Of the fingering information generated by the function to be generated, a difficulty level calculation function for calculating a difficulty level in performing fingering indicated by fingering information excluding fingering information searched by the search function ;
A function for correcting fingering information generated by the function to be generated based on the degree of difficulty calculated by the function to be calculated;
A program to realize
