Thumbs uses a single plucked sound from a Balinese thumb piano as its primary sound source, subjected to transformations of pitch and grain, and explored in multichannel space. I aimed to reduce the variety of sound-types and materials used in the work as much as possible, while still creating an engaging and evolving soundworld. A number of spoken expressions that include ‘thumb’ came to mind during the composition of the piece (rule-of-thumb, all-thumbs, thumbing through, thumbs-up / down, under thumb). These acted, at some level, as informers upon the work.
