Semblance


Semblance is an electroacoustic composition ensuing from a research dissertation on the subject of audio manipulation and tension in selected works of Australian composer Ben Frost. The composition primarily comprises an auditory collage of acoustic sound files which have been manipulated using the Audacity, Spear, Supercollider and Pro­tools computer programs to affect pitch, frequency, timbre and amplitude. An acoustic upright piano, a 1970’s Micromoog synthesiser and a selection of analogue outboard effects units were also employed to augment the sonic content of the composition. The goal of the piece is to induce a feeling of tension, uncertainty and apprehension in the listener.
