Abstract
An electronic musical instrument comprises a power source switch, a keyboard including a plurality of key switches corresponding to a plurality of keys, a signal generator for generating a musical tone signal corresponding to a note of a depressed key, and a loudspeaker driven by an output of the signal generator for producing a musical tone. In the instrument, the power source switch is interlocked with the key depression operation so as to supply power to the electronic musical instrument only when a key is depressed.
