AEOLIAN TREE is an electromagnetic–kinetic antenna sound sculpture and ritual performance under a tree. The ritual frames the work: a practice of caretaking and shared attention that treats the tree as a sacred, living archive—a portal between spiritual and physical worlds, between ancestors and the present.

Three pendulum antennas, each hung from a separate branch, form a triadic constellation around the trunk. This geometry holds harmonic symmetry and gentle dissonance, centering the tree as the anchor where natural, technological, and human rhythms meet.

Each pendulum carries a small magnet bob above a floor‑mounted coil. Acting as electromagnetic Aeolian harps, their motion gathers the site’s invisible “winds” of radio energy; the swing imprints slow polarity changes and gentle Doppler bends onto the received spectrum. Each antenna feeds a software‑defined radio; signals are shaped in SuperCollider and diffused on small speakers in a listening ring beyond the pendulums.

The work moves between a quiet, all‑day installation and a three‑part ritual—Listening/Translation, Invocation, Transmission/Closure. In performance, Thrän engages antennas and voice while collective voicing invites visitors to whisper, forming a temporary choir. Non‑invasive rigging, minimal intervention, and shared authorship enact care, opening a brief portal between human, tree, and signal.
