Audialsense
26 – 28 March 2010
Audialsense will set up a site-specific installation in the main lecture hall at the Department of Architecture and Spatial Design, London Metropolitan University, filling the space with dense chords of pure tone which will be held for three days. The frequencies of the sine waves are based on the wavelengths associated with the dimensions of the room. This is a long duration piece allowing visitors to walk amongst the standing waves, immersed in a soundscape of changing amplitudes and harmonies.
“We were to be working alongside a 40 strong choir, so a starting point for the piece was Thomas Tallis’s ‘Spem In Alium’, an early choral work for 40 voices, and of exceptional power. We isolated the wavelengths of the room, the length, width and height, and added the 167hz tone of an especially noisy air duct within the space. With four base-tones to work with, we added nine subsequent chromatic overtones to each of the room tones, giving an output of four banks of 10 tones – 40 sine waves – a similar mapping to ‘Spem In Alium’. The tones were then played back into the space, and held for three days, creating fleeting standing wave phenomena, emerging tonal chords and rhythms.”
