Mark Trayle, born Mark Evan Garrabrant (January 17, 1955, in San Jose, California – February 18, 2015, in Ventura, California) was a California-based musician and sound artist working in a variety of media including live electronic music, improvisation, installations, and compositions for chamber ensembles.

His work has been noted for its use of re-engineered consumer products and cultural artifacts as interfaces for electronic music performances and networked media installations.

Under Berhman's tutelage, he began building hybrid digital-analog electronics and used those (often with electric guitar and homemade performance interfaces) throughout the 1980s.

True North, Periodic Transmissions at Regular Intervals (are not allowed), and Propagation, Reflection, and Absorption are entirely acoustic in nature but use electronics and sensors to create real-time scores for the performers.

Trayle has performed and exhibited at experimental music and new media venues and festivals in the U.S., Canada, and Europe.
