A musical instrument with novel configurations and performance techniques that can play notes and scale tones is disclosed. The musical instrument implements design and ergonomic changes to a Theremin's traditional configuration and use. The musical instrument includes an additional sound generation device such as an actuator that is operated to provide rhythm and tonal results. The musical instrument includes a pitch antenna that is configured in a horizontal position, which creates a different plane of reference with respect to performance motions employed for modifying the pitch. The musical instrument allows for a user to play notes and scale tones in a standing, seated, or ambulatory position. Improved playing interfaces, accessory items, and other characteristics for enhancing the playing of the musical instrument are provided.

Methods and systems for generating oscillatory timbres for musical synthesis through synchronous ring modulation are described. An example method performing hard synchronization comprising using first and second oscillators, the first oscillator being a fundamental oscillator which provides a fundamental frequency, the second oscillator being a modulation oscillator operable at a frequencies higher than the first oscillator; and in response to the fundamental oscillator completing its cycle, synchronizing the modulation oscillator to the original point of its waveform. Ring modulation may be performed on the synchronized output by multiplying it by a waveform of the fundamental oscillator, such that the ring modulation is synchronized to produce a variety of oscillatory timbres. The method can create a variety of unique sounds having musically pleasing characteristics. A real-time audio signal can be used instead of the first oscillator to produce dynamically varying timbres.
