American composer and pioneer of indeterminacy
The John Cage Organ Project Halberstadt has added an A4 pipe, marking a rare eighth-note change in the 639-year performance. Since 2001, the piece has sounded in Halberstadt’s Burchardi Church, with a cadence that is slated to end in 2640. Organ sound now evolves as a new note enters the acoustic space, a moment observers say resonates through visitors.
