The Broken Cathedral of Christchurch is an ambient poly-tuning piece using 11, 12, and 19 notes to the octave. The instruments used are a Korg MS2000 synthesizer, 19 edo electric guitar (several tracks), and 5 string bass – all with liberal application of effects, mixing, and mastering. The piece is dedicated to the Anglican cathedral of Christchurch New Zealand which will be brought down and rebuilt due to extensive earthquake damage.
