ABSTRACT:
An electronic musical instrument allows the performer to control tone volume of a rhythmic tone by a simple manipulation of keys of a keyboard. The electronic musical instrument comprises a rhythmic tone generator including a plurality of tone sources, to which a group of keys of the keyboard are assigned, respectively. Each of the tone sources generates a rhythmic tone when a corresponding one of the group of keys is depressed. When it is desired to give an accent to the rhythmic tone, a key adjacent the depressed tone source designating key is additionally depressed. This multiple key-depression is detected by a detection circuit. Tone volume of the rhythmic tone generated by the tone source is controlled in accordance with the detection of the multiple key-depression.
