Notes: Commisioned by the Guidonian Hand Trombone Quartet. FeedbackTree posits a line drawing tree shape created with a procedural drawing program. The tree form is rotated horizonatlly and positioned over the range of the trombone (a score diagram reveals this). Dividing the material among four players, a continuous gliss is the underlying concept. The scoring uses various sonic textures to change the reinforce the sonic arc of the piece. The use of the word feedback in the title refers to the feedback loop used for the iterative drawing process.
