Barry Hall is active in many types of music including medieval, Celtic, jazz, new music and electronic. His performances throughout North America and Europe have ranged from an exhibition of historical English folk music at the Smithsonian Institution to a contemporary electric violin concerto with interactive electronics performed at the World Music Days in Mexico City. Barry plays a variety of instruments including violin, medieval vielle, electric violin, bass, didjeridu and percussion in a number of musical groups, including Trouz Bras, The Janus Ensemble, Qwire, Free Energy, Coro Hispano de San Francisco and The Hall Consort. He studied composition with Eliot Newsome at Westminster College, where he earned a BS in Mathematics and Computer Science (Magna Cum Laude) in 1985. In conjunction with Dr. Daniel Oppenheim at Stanford University's Center for Computer Research in Music and Acoustics (CCRMA), and the IBM music research center, Barry has worked extensively in the development of interactive musical software that interacts with a solo performer in an improvisational manner. He performed the world premiere of Dr. Oppenheim's Concerto in D for MIDI violin and Dmix interactive software (sound samples). Their work in this area was featured on BBC Television's Open University. Collecting and building musical instruments is one of Barry's passions. He specializes in building unusual ceramic musical instruments and performing on them with his group Burnt Earth. Barry author
