Electronic musical instrument

Instrument that uses electronic circuits to make sound

An electronic musical instrument or electrophone is a musical instrument that produces sound using electronic circuitry. Such an instrument sounds by outputting an electrical, electronic or digital audio signal that ultimately is plugged into a power amplifier which drives a loudspeaker, creating the sound heard by the performer and listener. An electronic instrument may include a user interface for controlling its sound, often by adjusting the pitch, frequency, or duration of each note.
