A keytar is a relatively lightweight electronic 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 strap. Keytars allow players a greater range of movement onstage, compared to conventional keyboards, which are placed on stationary stands or which are part of heavy, floor-mounted structures. The instrument has a musical keyboard for triggering musical notes and sounds. Controls are placed on the instrument's "neck", including those for pitch bends, vibrato, portamento, and sustain.
