Harnessing nature’s music
The Singing Ringing Tree is a wind powered sound sculpture resembling a tree set in the landscape of the Pennine hill range in Lancashire, England. The 3-metre tall construction comprising pipes of galvanised steel harnesses the energy of the wind to produce a penetrating choral sound covering a range of several octaves.
The Art Dive 
Mira Tudor, Thank you for the information and the link. Does anyone indicate which ranges the octaves fall in? The sculpture relays the look (and almost the feel) of a wind-beaten woody plant.
