Mike Tonkin and Anna Liu of Tonkin Liu. The Singing Ringing Tree.

A 3-meter-tall, wind-powered musical sculpture made of galvanized steel pipes, it stands high above the English town of Burnley. The pipes swirl to form the shape of a tree bent and blown by the wind, and produce an eerie, melodious hum as the constant wind on Crown Point drifts through them. The Singing Ringing Tree’s pipes are used for both aesthetic qualities as well as for tuning, with their sound varied according to length and added narrow slits on the underside of specific pipes. The sound produced by these twisted metal trees covers several octaves and is said to be simultaneously discordant and melancholy, and intensely beautiful. Designed by architects Mike Tonkin and Anna Liu of Tonkin Liu. (via Interactive Architecture)
