Buoyancy was composed at the McGill University EMS using acoustic cello sounds exclusively. These were modified by speed changes, tape echo, layering, pitch to voltage conversion, ring modulation and filtering. White noise was produced by recording the highly amplified sound of the bow moving lightly on a string.
