So it seems that that kind of fipple head joint gets you a two-and-a-bit octave ‘chromatic whistle’, but the shakuhachi end-blown head joint would retain more of the quality and range of the original flute? (Why is that?)
'cause it really is a flute, not a whistle. No fipple and windway to focus air to the blade- you have the make the embouchre yourself. It does have a more focused, thin tone though, closer to the whistle. Personally I think it’s a lot harder to get a sound out of a shakuhachi or quena than a transverse flute.
There seems to be at least one person making shakuhachi of pvc, but he says he does not make them to go into Boehm flutes. And it looks quite a difficult undertaking to make such a blowing edge:
I make simple notch-flutes out of PVC; you can get a good notch pretty easily. Either just whittle away, or drill a hole, cut of a bit less than half the hole, and then whittle away. My results look pretty crude, even after sanding; but the point is, they work! (and sound pretty nice in my humble opinion)
But then again, that fella’s results are probably much better quality. I’ll definately have to try that sometime. But the point is, with a drill, saw, knife, some sandpaper, and a few hours you can make a fun little notch-flute for yerself, and assumedly a mouthpiece for your Boehm too (that’s another project I’ll have to try), given the right width of tubing. You can also use a hammer to sorta simulate the conical bore of the boehm headpiece, though I don’t think it does this perfectly.
