Artscape/Exotic Hypnotic: Global Tranquility (Sam Burt & Ensemble)

Global Tranquility @ Artscape/Exotic Hypnotic, Langsdale Auditorium, July 22, 2007, Baltimore, MD

The Sam Burt portion of this marathon concert featured music for sine tones. The first piece was an electronic work featuring restless sine tones in various frequency ranges relative to one another - creating difference tones that were particularly audible if one was close to the center of the stereo field. The "pure" frequencies of sine tones handled this way creates an interesting contour of precise smoothness and roughness that was definitely the focus of this work.

The second piece was for string quartet and sine tones and it was the string quartet that put some horse hair on these sine timbres. With long sustained tones pitted against computer generated "pure" tones this piece was an austere study of the harmonic potential of lock-step consonance combined with the beating and combinatorial tones rising from deliberate de-tunings of such consonance.
