Composed especially for the main hall of the Orgelpark in Amsterdam, with its historical organs, Descendants was realized in the just-intonation “Dreyblatt” tuning system, derived from the first eleven harmonic overtones and their extensions based on the fundamental C (A = 415 Hz). The following intervals, identified on the four organs and corresponding to my tuning system, were used in the composition: 1/1, 9/4, 3/2, 7/4, 11/16, 21/16, 25/16, 35/32, 63/32, 77/64, and 81/64. These pitches and their registers were organized into five sections and distributed across four different historical and contemporary pipe organs in the space, filling the hall with gradually shifting resonances.

"The composition offers a highly immersive listening experience with elusive sensibilities of time and space. The sustained, ethereal sounds of the four organs filled Orgelpark’s main hall with gradually changing resonances. Orgelpark sounded like a vivid, vulnerable entity, as if it were breathing with its own independent, almost static pulse. "
