In this study, a noise-veiled chord progression with slowly oscillating trills is grafted onto the upper harmonic structure of a ‘hidden’ chorale melody that lies below the lower limit of audible frequency. The majority of recorded sounds utilized in "Vestige" were produced by bowing string instruments (guitars, mandolin, banjo, phonoharp, and e-bowed dulcimer). Noise and artifacts resulting from bowing with unstable materials pervades the composition. Sustained tones from the reeds of a pump organ are also present. All recordings were made by the composer and carefully re-tuned to match the construct of the hidden model.
