OK, so... I'm building a fountain and a pond in the back yard and I got the idea of putting some water chimes in it. I've ordered some 2 inch copper floats. The floats will bob about in the water and bump up against copper pipes (chimes) that will be suspended horizontally just above the surface of the water.
So far, so good, right?
I'm using common 1" copper plumbing pipe for the chimes. My question is - what's the formula for calculating how long to cut the pipe to produce a particular pitch?
I did some googling and found a formula for cutting other chimes based on a reference chime, but nothing that tells me an absolute frequency.
Any thoughts?
