for trombone (2005)
with computer sound
duration is 12′

Aes/Aer (“Brass/Atmosphere”) is a composition for trombone and computer sound written for virtuosic performer, Haim Avitsur. The piece explores the material aspects of the trombone through physical preparations of the instrument and virtual augmentation of certain characteristics of the instrumentation. Various glissandi, multiphonic effects and microtonal melodic systems are expanded with the computer in an attempt to extend the reach of the instrument into the virtual space. In this way the electronics are treated as an extension of the embodied instrument. Further, the trombone is prepared with sheets of thin metal (in the form of tinfoil) creating buzzing metallic effects. Sheets of tinfoil suspended on the stage allow the performer to move the projected sound in and out of resonant metallic areas. The metal preparations act as an axis between the virtual and physical spaces, an abstraction of the instrument as material. Aes/Aer is a celebration of both the forceful and lyrical characteristics of this marvelous instrument.
