Quartet For Viola, Cello, and Digital Processor

premiered April 26, 1993

Cynthia Fogg, viola; Tom Flaherty, cello


“Digital processing turns a viola and a cello into a quartet in Tom Flaherty's Quartet for Viola, Cello and Digital Processor. Through time delay and pitch transposition the viola is fractured into a trio with itself. The viola is the star, preening in front of a three-way mirror, while the cello lays down the velveteen cushion. The piece is both pretty and fun.” [Dinosaur Annex]
– Richard Dyer, The Boston Globe

Quartet For Viola, Cello, and Digital Processor is the second in a series of pieces for acoustic instruments and digital processor, in which my object has been to make maximum use of the simplest algorithms. In Quartet, the viola is the principal voice; its output is constantly delayed and transposed (down a whole step in one channel, up a half step in the other.) When the delay pattern is overlaid with further live playing several different tempi and meters emerge from the composite, although delay times (and transpositions) are actually constant throughout the piece. The cello plays a supportive role, and its only electronic modification is a slight flanging and phasing that is most noticeable the during longer notes at the end of the piece. Quartet is lovingly dedicated to my wife and performing partner, Cynthia Fogg.

Quartet can be heard on Bridge Records, SEAMUS Recordings, and iTunes.
