ABSTRACT:
An electronic musical instrument has a keyboard and a sound source circuit for manual performance along with automatic accompaniment. A memory is provided for memorizing a plurality of rhythm patterns of the automatic accompaniment such as introduction, normal, fill-in and ending. The memory further stores timbre codes corresponding to the respective rhythm patterns, effective to specify tone color of the manual performance. Selecting switches are manually operated during the manual performance for selecting a desired rhythm pattern. A CPU accesses the memory to retrieve the selected rhythm pattern so as to switch the automatic accompaniment to the selected rhythm pattern. The CPU concurrently controls the sound source circuit to change the tone color of the manual performance according to a particular timbre code associated to the selected rhythm pattern.
