Designed by Mike Tonkin and Anna Liu, the Singing Ringing Tree is a sound sculpture made of steel pipes that looms over fields near Burnley in England. Its song changes depending on the direction of the wind, but is always discordant and droning.
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.
In 2007, the sculpture won (along with 13 other candidates) the National Award of the Royal Institute of British Architects (RIBA) for architectural excellence.
"The hills are alive with the sound of terror."
Good video of the tree is annoyingly scarce. This one is marred by wind noise on the mic. This one has inane library music played over the tree's music. The one below is good but sadly short. The tree is happy. The tree has eaten well.
Here's another fine but too-short video emphasizing the vague menace of the West Pennine moors.
