Abstract

An automatic performance device has a phrase performance information memory storing pieces of phrase performance information having predetermined phrase lengths, which each have phrase-discriminating information imparted thereto. A performance pattern memory stores pieces of performance pattern information for determining a sequence of performance of the pieces of phrase performance information. A CPU prepares pieces of performance pattern information by storing the pieces of phrase-discriminating information into the performance pattern memory in a sequence of performance of the pieces of phrase performance information, according to operation by an operator, and imparts to the prepared pieces of performance pattern information as many pieces of pattern-discriminating information. Pieces of performance pattern information are designated by means of the pattern-discriminating information. Then, the CPU reads out pieces of phrase-discriminating information for phrases of the designated pieces of performance pattern information in the performance sequence from the performance pattern memory, and reads out pieces of phrase performance information corresponding to the read-out pieces of phrase-discriminating information, to give automatic performance based on the read-out pieces of phrase performance information. A chord of any of the pieces of phrase performance information to be set in performance thereof can be designated, and the CPU changes a note of the read-out phrase performance information according to the designated chord.
