Hats was inspired by a dancer wearing a hat moving through a large space. The multimedia composition is comprised of acoustic and electronic sound integrated with the visual palettes resulting in a timbral, dynamic and spatial composition. A layering of pitches is obtained from the whole range of the Bass and Bb clarinets through a multiple sound approach focusing on a central pitch. A continuous pulse is created with clarinets through sub-tones and overtones using quarter notes, monophonics and multiphonics. Real-time Audio Mulching, enabled by the computer interface, contributes further to the possibilities of a sonic world of layered clarinet, subtones and pulse fragmented overtones throughout the composition.
