Abstract
An electronic musical instrument is provided with an ad-lib melody data storage device for storing ad-lib melody data and an ad-lib switch so that, when the ad-lib switch is turned on, it will read the ad-lib melody data to automatically play an ad-lib melody. The access to the ad-lib melody data is performed according to a clock value, and the instrument is adapted to count up the clock value while the ad-lib switch is on, and moreover to hold or count up without resetting also while the ad-lib switch is off. This arrangement allows the reading start address to be varied each time the ad-lib switch is turned on, enabling ad-lib melodies to be played in great variety.
