Abstract:
A performance position detection method comprising:a reception step of receiving real-time performance data; a step of supplying reference performance data of a given music piece; an estimation step of estimating a performance position, in the music piece, of the real-time performance data, with reference to the reference performance data; a determination step of identifying performance data to be performed following the performance position estimated on the basis of the reference performance data, and determining accuracy of the estimated performance position in accordance with whether or not performance data corresponding to the identified performance data is actually received as next real-time performance data by said reception step; a step of identifying a tempo of performance based on the real-time performance data when the estimated performance position is determined as accurate by said determination step; and a management step of executing predictive management of timewise progression of the real-time performance in accordance with the tempo identified by said determination step, wherein the predictive management of timewise progression of the real-time performance by said management step is modified in accordance with the estimated performance position each time the estimated performance position is determined as accurate by said determination step.
