An optoelectronic pickup of a musical instrument comprising:
- at least one light source positioned to direct light to impinge a sound producing element of the musical instrument;
- and
- at least one photoreceiver positioned relative to the at least one light source to detect reflected light from the sound producing element;
- wherein the pickup is configured to measure a position of the sound producing element using a characteristic of a beam pattern produced by the at least one light source.
