A system and methods which allow even a novice performer to easily play music which is not disharmonious and which is pleasing to the performer and his or her audience. The music is preferably created by a performer breaking one or more beams of light, which are emitted by one or more beam emitters and received, or detected, by one or more beam detectors. When a beam detector determines that a beam has been broken, a trigger is sent to a synthesizer, with such synthesizer preferably being a computer interfaced to the beam detectors via a Universal Serial Bus connection. The synthesizer selects from one or more electronic sounds, based on a pre-programmed collection of sounds, and a sound generator, such as an amplifier and speakers, plays the sound.
