ABSTRACT:
An automatic rhythm performance device is constructed of a rhythm pattern memory, an instrument memory and a rhythm tone generator. The rhythm pattern memory delivers a variety of rhythm patterns corresponding to the selected rhythm. The instrument memory delivers instrument names of instruments to be performed corresponding to the selected rhythm too. The rhythm tone generator generates percussive instrument tones of the delivered instrument names at the timing designated by the corresponding rhythm patterns, respectively. In the above rhythm performance device, the selectable rhythms are grouped into some groups in advance. This grouping enables the instrument memory to be constructed of two stage memories. One stores group numbers identifying such groups, and the other stores the instrument names in every such group. The delivery of the instrument names is performed by addressing by the outputted group number to which the selected rhythm belongs. This double stage memory construction need less storage areas about storing the instrument names to be performed.
