Abstract
An automatic performance apparatus extracts characteristic data indicating individuality of performance of a player from performance data, compensates for score data exhibiting no individuality by the characteristic data, and executes an automatic performance using the compensated data. The apparatus includes a characteristic extraction unit and a characteristic regeneration unit. The characteristic extraction unit extracts characteristic data on the basis of a correlation between performance data and score data, and stores the extracted data in a characteristic data storage unit. The characteristic data is extracted with regard to styles of performance in association with notes, signs attached to the notes, dynamic marks, tempo marks, the general flow of music, and the like with reference to score data exhibiting no individuality. The characteristic regeneration unit compensates for arbitrary score data with the stored characteristic data to generate performance data. An electronic musical instrument is controlled based on the performance data, thereby obtaining automatic performance tones exhibiting the individuality of the player.
