The Pyrophone is an acoustic sound sculpture performance that utilises the theories of thermo-acoustics to produce drone tones. Like a pipe organ, the pyrophone operates by moving air through long tubes. However, instead of blowing air, a high temperature flame is applied to one end of the tube (by a welding torch) and the resultant change in air pressure creates a slightly sinister yet soothingly meditative drone. Metal pipes were cut to specific lengths and attached to a rebar carriage in order to create a twelve-note chromatic C scale. Spectators were invited to take part in the performance, resulting in a fiery co-creative sound sculpture spectacle.
