Abstract
In an electronic musical instrument, a key operation detecting section detects a key operation on a keyboard, and the hand key operation contains a key pushing operation and a key releasing operation. A control unit detects a chord of a chord part in response to the key pushing operation and the key releasing operation. Then, the control unit generates chord control data for a re-trigger operation based on the detected chord of the chord part, when the key operation is the key pushing operation. A sound generating section generates a new accompaniment sound based on the chord control data and automatic accompaniment data stored in a memory section in the re-trigger operation.
