Abstract
This invention discloses an electronic musical instrument incorporating an auto-accompaniment apparatus, which can desirably set a tempo of rhythm accompaniment tones (e.g., chord, bass, and drum accompaniment tones) using a tempo preset button or an increment/decrement button during a play operation. The read speed of an auto-accompaniment data memory is determined on the basis of the set tempo. A tempo controller for switching from the current tempo to a new tempo upon detection of a division of a bar of auto-accompaniment data is arranged, thereby eliminating uneasy feeling upon switching of tempo.
