The Singing Ringing Tree by Mike Tonkin and Anna Liu of Tonkin Liu
The Singing-Ringing Tree at Crown Point high above Burnley in the UK is a three meter tall wind-powered musical sculpture constructed of galvanized steel pipes. The constant wind on Crown Point produces an eerie, melodious hum as it drifts through the pipes. 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 it is said to be simultaneously discordant and melancholy, and intensely beautiful. The piece was designed by architects Mike Tonkin and Anna Liu.
