18. An automatic accompaniment performance apparatus, comprising:
-
memory means for storing automatic performance data for a plurality of accompaniment sections of a musical piece; designating means for designating a selected accompaniment section; determining means for determining whether one of said plurality of accompaniment sections stored is said memory corresponds to said selected accompaniment section designated by said designating means; changeover means for changing said selected accompaniment section to a predetermined replacement accompaniment section selected from said plurality of accompaniment sections stored in said memory means when said determining means determines that said selected accompaniment section does not correspond to one of said plurality of accompaniment sections stored is said memory means; reading means for reading said automatic accompaniment performance data for at least one of said replacement accompaniment section when said determining means finds no correspondence and said one accompaniment section that corresponds to said selected accompaniment section section when said determining means finds a correspondence; and output means for delivering musical tone information based on said automatic accompaniment performance data read by said reading means. - View Dependent Claims (19)
