The Hang Point is also in millimeters,
- It's .2242 times the overall length of the tube.
Each note is greater or lesser than its neighbour in frequency by the twelfth root of two times its neighbour's frequency.
F2 = F1(2^1/12)) or F2 = F1/(2^1/12))
Similarly L2 = L1(SQRT(2^1/12)) or L2 = L1/(SQRT(2^1/12))
THIS BIT IS IMPORTANT FOR THIS REASON:
If you have a given length of tubing, or a bunch of tubes of various lengths, you may want to just use them as efficiently as possible (i.
