Kim Cascone - Lunar Mansions

Kim Cascone. Lunar Mansions - for Organ & Sine Waves.
Recorded 29 October 2014, Union Chapel, London

artist statement:
“Lunar Mansions,” a twenty-one minute drone piece commissioned for the Union Chapel Henry Willis Organ, continues my recent work with low-frequency difference tones (beats) and meditative states of consciousness.
The intent of this piece is to provide an “aqua sonus” of undulating frequencies created by the difference between the tuning systems of the Union Chapel pipe organ, tuned in equal temperament, and computer generated sine waves that are tuned in just intonation.
This effect will, hopefully, fill the Union Chapel with pulsating frequencies creating acoustic Moire patterns and conjuring associations and visuals for the listener. The piece will be played in darkness for a meditating audience.
