The entire piece is based on a time measurement of one breathing cycle of the performer. The performer breathes through the saxophone at the beginning of the piece to model the first section. Reproduced at multiple scales, the gesture generates all aspects of the piece. A driving force of the development of the entire piece is the proportion between time periods of inhaling and exhaling. The ratio generates a metric module projected to the relationship between sounds, sections and large scale design. Dynamics and sound density constantly oscillate from an almost imperceptible level to full intensity followed by the decrease and arrest. I am thankful to Kent O’Doherty who dedicated much time to search and invent sounds that would best bring out the concept of the piece.
