BB,

The Chiff & Fipple Site had some articles or links on modern metal whistle makers perturbing whistles - even remember seeing some very basic articles somewhere on the web a while ago about some basic tips, including polishing some areas of the bore. The Forum there had some stuff on that too a while ago, I seem to remember. If anybody locates the stuff, please post a link here, as I have lost all my old stuff.

[I probably hadn't really made the whistle's mouthpiece all that smooth and even at this stage, so it may have been "richer" in overtones than a smoothly crafted low whistle, and thus more responsive to this type of modulation]

Interesting point that I had not directly thought about...
