Friction (2011) is the force that resists motion in materials in contact. This composition explores sounds and motions which act as a metaphor for various elements surrounding friction, such as a sense of kinetic energy and the resulting release of heat. In particular, the piece references internal friction, the force resisting motion in solids which are undergoing deformation.
I imagine this process in the sounds from the sliding trombone, which appear to push against some kind of imaginary sonic barrier. The materials become less and less stable as the musical atoms within the composition distort and split up. Once separated, the material reforms into new but related shapes. It is as though the new material reveals the original context, and draws us inside.
