Abstract

A motif performing apparatus for use in an electronic musical instrument, which effects an automatic performance of a motif only while sounds are being radiated. The motif performing apparatus is able to store information representing motifs to be played, and to read and output information representing each of the motifs, separately, while instruction units for instructing a radiation of musical sounds are operated. Accordingly, even if the operation of an instruction unit is unchanged, the performance is varied according to a pattern of the information. Further, as long as the instruction unit is operated, a plurality of musical sounds are generated automatically and sequentially according to the pattern of the information, and thus a performance can be easily effected. Furthermore, the motif performing apparatus can effect the automatic performance only while the instruction unit is operated, and therefore, the automatic performance can be stopped at any time by stopping the operation of the instruction unit, and thus the player can play the electronic musical instrument while effecting an automatic performance by operating the instruction unit.
