Abstract
Abstract An electronic musical instrument comprises devices for inputting rhythm and melody play patterns. The rhythm and melody play patterns are stored in a pattern memory such that the rhythm and melody play patterns are in a timed relation to each other. The rhythm and melody play patterns are simultaneously read out from said pattern memory so that rhythm tones and melody tones are sounded according to the rhythm and melody play patterns.
