Title:
MUSIC PIECE DATA PROCESSING METHOD AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2018/016581
Kind Code:
A1
Abstract:
This music piece data processing device estimates a musical performance location in a music piece through analysis of a sound signal indicating a musical performance sound, and updates the tempo specified by music piece data indicating the performance content of the music piece such that a tracking of tempo is in accordance with transition of the dispersion of a musical performance tempo generated from the result of estimating the musical performance location for multiple times of performances of the music piece and transition of the dispersion of a reference tempo prepared in advance. In the updating of the music piece data, the music piece data processing device updates the tempo specified by the music piece data such that the musical performance tempo is preferentially reflected in a part of the music piece where the dispersion of the musical performance tempo is lower than the dispersion of the reference tempo and such that the reference tempo is preferentially reflected in a part in which the dispersion of the musical performance tempo is higher than the dispersion of the reference tempo.
