ABSTRACT:
An automatic performance apparatus which records a performance state in the form of performance data in a storage means, and plays back a performance based on the performance data read out from the storage means In a record mode, a chord detection means discriminates whether or not a chord has been established. If a chord has been established, then chord information is written in memory. If a chord has not been established, then tone information including key-on information or a note portion of key-on information, excluding octave information, is written in memory. The automatic performance apparatus enables the use of a storage means having a greatly reduced storage capacity as compared to a prior art one, and pitch or note information designated at a keyboard or the like are recorded/played back as performance data without modification.
