Interesting water-gap!
Stan Meyer 0.0950 inch = 2.4 millimeters
Peter Davey 0.0826 inch = 2.1 millimeters
Looks like Peter used "Three" frequencies: 350, 49, 1000Hz
So there must be a "key note" for the water molecule and use this fundamental frequency and put harmonic on it or enharmonic ?

If you have a fundamental frequency (sinewave) and then put a harmonic (sinewave) on the fundamental we get a new shape.
"There are several important aspects to this new shape.
First, its shape is not a simple sine wave, so it will sound richer than just a pure tone.
Second, even though the shape is different, the period and frequency are the same as the fundamental above.
This is very important, because it means that the pitch stays the same.
So, now we can see the connection between shape, harmonics and tone quality.
If add harmonics to the fundamental, we change the shape of the wave, but not its pitch, so this gives us a way of independently controlling the tone quality without affecting the pitch. It does not matter if we add a wave at 3f, 7f, or 32f. The shape will change but the pitch will not."
