Jacob A. Barton (b. 1985) is a composer and multi-instrumentalist whose work focuses on xenharmonic practice and theory. Barton studied composition at Rice University and the interrelation between tuning, cybernetics, performance, and social change at the School for Designing a Society. In 2005, Barton serendipitously invented the "udderbot", a low-cost, low-tech water-slide woodwind. He has since tried out the udderbot on a variety of musical contexts: in old-time string band and jug band music; on humanitarian clown trips to Ecuador and Costa Rica with the Gesundheit! Institute; as part of water-themed multimedia collaborations with the Change of State Performance Project; and in a music video featuring microtonally-bent Christmas carols. In recent years he has organized the Oddmusic Instrument Library, an "Udderbot Marching Choir", and Xenharmonic Praxis Summer Camp.
