About

Based on a 250 year old experimental musical instrument, Hubbub Music’s Pyrophone Juggernaut is the largest hand operated multi octave fire organ in the world. Deep growls, atavistic moans and even coral sounding timbres combine with epic bell cords, industrial drums and acoustic thongaphone bass.

3 Giant flame instruments (spanning 12 metres long x 9 metres high), made from stainless steel, copper and aluminium create unearthly music in concert. Perched on top of a shipping container and designed to set sail, the fire organ is accompanied by massive, tuned freight liner alloy wheels, sub-frequency metallophones, fire infused truck horns and a giant gong.

The flow from a combustion venturi (in our case, a hand-held trigger-regulated propane torch) excites the standing wave of a length of tube – a pressure wave that travels to the end of the tube and partially reflects back, as in an open-ended organ pipe. This resonates the fundamental pitch of the length of pipe.

It has been discovered a number of variables can affect the timbre and pitch of the sounds, such as size, pressure and depth of penetration of the flame source and fluctuations of air temperature.   Frequencies produced can double or halve, and under- or over-blowing can accentuate the different harmonics of each flame tube.
