The Singing Ringing Tree is a unique wind powered sound sculpture resembling a tree set in the landscape of the Pennine mountain range overlooking Burnley, in Lancashire. Designed by architects Mike Tonkin and Anna Liu of Tonkin Liu, the Singing Ringing Tree is a 3 meter tall construction comprising pipes of galvanised steel which harness the energy of the wind to produce a low and mellow hum. The harmonic and singing qualities of the tree were produced by tuning the pipes according to their length by adding holes to the underside of each.
Completed in 2006, it is part of the series of four sculptures within the Panopticons arts and regeneration project created by the East Lancashire Environmental Arts Network.
