slow/noise/tone for solo electric guitar is a semi-improvisational work in which the guitar is tuned to produce pitches in a 24-tone equal tempered scale. The piece is structured around a series of “moments” which vary in length and content, and extremes of timbre, volume, and pitch. The material varies between extremely inaudible to loud sounds, and strict pitch series to more open-ended processes of generating noise. Various levels of “beat” interference occur as well, as additional layers of depth in the sound.
