A little about the Quena (kee nah)
The sound notch
The notch in the end of the quena is very important.
If you make it too shallow you will be able to play the upper
octaves ok but have a tough time in fundamental octave.
If you make it too deep it will play the lower octave loud and
clear but you will have to really use your embouchure to squeeze
out the upper octave high notes. I have tried several and
regardless of which way you make it, you will learn to adjust
to having it that way. When i play on the quena, and switch
from one to another that is built differently, it always takes
me a bit to adjust to the feel of the new one. The
same embouchure does not work to produce the same quality of note.
The reason is that the mouth and lips specifically become part
of the instrument when you play it. Every thing you
do effects the sound: the distance of the lips from the notch
edge, the width and thickness of the air stream, the angle the
angle of the air stream across the notch, the velocity of the
breath and how much of it intentionally is blown past the
notch, etc... all have a big effect on the resulting sounds.
And there is something else that i can not define that comes up
from inside and allows the sound to happen. it is more of
a confidence that is so natural you pick up the quena and the
first note you blow is true and clear and sweet sounding.
It is a strange thing that i can not get by trying hard.
Another paradox here. The harder i try, the less often it
happens. When i almost unconsciously pick it up and start
playing, then that is the time it happens. Being logical
and thinking of all the little things that effect the sound never
help me find the "spot" when playing. It has to be intuitive
for me and automatic.
Once again, apologies for not having this section finished. Until i get around to it
you can use the information from the penny whistle data to locate the holes.
