Decomposition Study is a collaborative process. The instrument featured here is an arciorgano, a special microtonal organo di legno with two manually operated bellows and 36-key octaves across two manuals, constructed according to Nicola Vicentino’s designs from 1555. The notes of the music, written according to the rules of canonic contrapunto alla mente, are passed between two organists while four other musicians disrupt and amplify the organ’s airflow, acting similarly to cellular enzymes in decaying organisms during the decompositional process called autolysis. The music is decomposed as it is played, re-composed as it is heard.
Performed and recorded on March 28, 2022 at the Hochschule für Musik, Basel, on the arciorgano and amplified through a 6-faced “Cube” speaker.
