A keytar is a relatively lightweight keyboard (with or without a built-in synthesizer) that is supported by a strap around the neck and shoulders, similar to the way a guitar is supported by a guitar strap. Keytars allow players a greater range of movement compared to conventional keyboards, which are placed on stands. The instrument has a musical keyboard for triggering musical notes and sounds. Controls for pitch bends, vibrato, portamento, and sustain are placed on the instrument’s “neck". The term "keytar" is a portmanteau of the words "keyboard" and "guitar." Keytars may either contain their own synthesis engines, or simply be controllers, triggering notes on another MIDI capable synthesizer.
