A polyphonic electronic musical instrument is provided wherein a keyboard is used to trigger arpeggiated chords which emulate a strumming guitar sound. Select keys are provided for selecting which notes are included in chords to be strummed. At least one triggering device is also provided for triggering chords. The triggering device is constructed to alternate between two trigger states. The triggering device may be a keyboard key, foot pedal, or other device. The instrument operates in such a fashion that two arpeggiated chords of alternating direction (ascending and descending) may be produced during, and at least partially as a result of, one triggering device cycle from one state to the other and back again.
