This paper reports on the development of an ongoing artistic project, the Kite Choir, as an æsthetic practice of attunement with the atmosphere. The Kite Choir is a practice that builds on traditions of singing kites. In these traditions, the sound-making device is carried aloft by the kite, giving voice to an assemblage brought to life by the wind. The Kite Choir instead extends the site of instrumentation along the entire kite line and reel, to promote a collaborative chain of agency between atmosphere and performer/pilot. The paper describes the unique sound instruments and score created for this project and their relation to time and place of performance, and concludes with a set of speculative questions on how this practice might develop in the future.
