Abstract
Performance data is generated by performing in real time a music piece starting at a desired performance position. Performance position, in the music piece, of the real-time performance data is estimated from reference performance data of the music piece. Performance data to be performed following the estimated position is identified, and accuracy of the estimated position is determined in accordance with whether performance data corresponding to the identified performance data is generated as next real-time performance data. Because the accuracy of the estimated position is determined after generation of the next real-time performance data, a performance position following the estimated position determined as accurate represents a current performance position. Score based on the reference performance data is shown on a display, and the current performance position in the real-time performance is indicated on the displayed score. The indication of the current performance position on the display is moved in accordance with the identified tempo.
