US 10,482,856 B2 · Automatic performance system, automatic performance method, and sign action learning method

Abstract

An automatic performance system includes a sign detector configured to detect a sign action of a performer performing a musical piece, a performance analyzer configured to sequentially estimates a performance position in the musical piece by analyzing an acoustic signal representing performed sound in parallel with the performance, and a performance controller configured to control an automatic performance device to carry out an automatic performance of the musical piece so that the automatic performance is synchronized with the sign action detected by the sign detector and a progress of the performance position estimated by the performance analyzer.

Dependent claims

An automatic performance system for a collaborative performance of a musical piece by at least one performer and an automatic performance device, the automatic performance system comprising:

a controller, including at least one processor or circuit, configured to execute a plurality of tasks, including:
a sign action detecting task that detects a sign action of the at least one performer performing the musical piece based on a received detection signal;
a performance analyzing task that estimates a performance position in the musical piece based on a received acoustic signal representing a performed sound generated currently by the at least one performer;
and
a display control task that controls a display device to display an image corresponding to performance contents at the performance position in the musical piece estimated by the performance analyzing task.
