Abstract
An automatic rhythm performance device of an electronic musical instrument having an expression pedal is constructed of an operation amount detector, a rhythm selector, and a rhythm tone generator. The operation amount detector detects the operation amount of the expression pedal. The rhythm selector selects a rhythm to be performance among a plurality of rhythms. The rhythm tone generator generates rhythm tones which have rhythm patterns determined by the selected rhythm respectively, the number of rhythm tones to be sounded increasing automatically in proportion to the operation amount. This increment of rhythm tones further enriches a musical tone produced by manual performance whose volume is increased by the expression pedal operation.
