Abstract
An automatic rhythm performing apparatus capable of producing a rhythmic tone of a plural-tone-source rhythmic musical instrument such as a snare drum comprises a plurality of signal producing devices which produce a plurality of rhythmic tone signals corresponding to the respective tone sources of the single instrument. A control device controls respective signal levels of the rhythmic tone signals and a combining device combined the rhythmic tone signals at signal levels controlled by the control device to provide a combined signal corresponding to the rhythmic tone of the instrument, thereby providing a desired volume relationship of the respective component tones constituting the whole rhythmic tone of the instrument.
