I have seen that the quena is "tapered" inside, i.e. the hole from the embouchure side is large while the hole on the other hand is small. If this is true, how is it possible to make a good quena from pvc ?
Thanks.
If by "tapered" you mean "conical", the only one I know of that's definitely made that way are the ones that Mark Hoza offers. All of the quenas I've seen in person are a cylindrical tube. They look like they were made with the end closed off, which is then opened up enough to get the tonic note in tune.
To make one with a totally open tube, I would think you just start off with extra length and then gradually remove material from the end until it's in tune.
The problem I've had with quenas is that the top 3 holes are all very large. The purpose of this, according to O Gaiteiro do Chicago, is to give lots of leeway for expression. I would like a quena that has holes #1 and #3 smaller than #2 (just like an Irish flute) so that I can cover them and still be able to play well (without a new learning curve to overcome).
I would also like a quena with a tuning slide. I can understand why these aren't usually present on quenas, since you have to press the end against your face in order to make the proper seal for playing it. I don't know how they can stay in proper tune without one though. The only way I've been able to play along with another quena player is if both of us are using instruments made by the same maker. And does it sharpen up as it warms up, like other flutes do?
