An automatic rhythm accompaniment system comprises memory units storing a plurality of rhythm patterns and a designating switch for selecting a desired rhythm pattern. A memory unit is further contained in the system for previously storing chord progress data and further storing control data to fill in an ad-lib rhythm. Therefore, the rhythm accompaniment system may perform the ad-lib rhythm in place of the rhythm pattern by the switch designation for each measure. Additionally, the accompaniment based on the chord progress data may also be performed automatically.
