Dia 15 VI 13 545 West 22 Street Dream House at Dia:Chelsea

535 West 22nd Street, New York NY 10011

The Sundara All-Star Band—composed of La Monte Young, Marian Zazeela, Jung Hee Choi, voices; Jon Catler, fretless guitar; Brad Catler, fretless bass; and Naren Budhkar, tabla—will perform Choi’s composition Tonecycle Base 30 Hz, 2:3:7 Vocal Version with 4:3 and 7:6 in a World Premiere of the ensemble as part of the Dia 15 VI 13 545 West 22 Street Dream House Sound and Light Environment by La Monte Young, Marian Zazeela and Jung Hee Choi and presented by Dia Art Foundation.

Tonecycle Base 30 Hz, 2:3:7 consists of the linear superposition of 77 sine wave frequencies, all ascending imperceptibly to fixed frequencies and then descending to the starting frequencies. In this composition, there are eleven groups of sine wave frequency components set in ratios based on the harmonics 2, 3 and 7. Each of the eleven groups has seven sine wave frequency components that have the same starting point. Each of these seven sine wave frequency components gradually separates from each of the other components over time while ascending at slightly different rates of speed, and then descending toward the starting frequencies, infinitely revolving as in circles. These extremely close frequencies and their harmonics constantly produce beat cycles that traverse through a continuum of phase angles.
