In most less modern pieces it's more desirable to change pitch by altering the angle of the airstream and perhaps the air speed. If one used the odd-center fingers on the open hole flutes, then they run the risk of playing a tad off focus on the tone which doesn't really solve the tuning issue because off-focus sounds out of tune anyway.
That being mentioned, I will often finger the high A3 with my LH mid finger a tad off the hole to raise the pitch.
As another point to mention, some people think that they should keep their raised fingers as close to the keys as possible when training their technique. Thus, only opening the keys and having the fingers very close or on top of the keys is their intent. I've tried this some but it actually serves no technical purpose whatsoever and as far as I'm concerned, it increases technical inaccuracy and under-trained fingers. If one is going to play like that, they may as well only use a closed hole flute.
Thanks i agree on that tone and technique. it just that it gets boring sometimes working on it and some other things on flute is more fun but still may serve while playing to some extent... or maybe not even on playing just things to do on a flute.
ex: if u play the f with the t1 and t2 key at the same time you get a strange note... can't place it.
I bought an open hole flute 2 months ago and it's like starting over. Every day it gets a lot easier. About a month ago I took off all the plugs. It's a big adjustment but worth it. I like both my Yahaha 221A and Yamaha 481. I'm finding that now when I play the 221 I'm doing a lot better. I ready somewhere on the internet that it takes about 2 months to get used to the open hole flute. I think that's about right. I still have a ways to go before I'm totally comfy with it.
yep i've had mine for about 1 year now it's good. i've gotten use to it except for the sometimes leak when i play the low d, d flat and c. because of the finger that's beside my pinky not sealing the hole
