I’ve been working on this since moving to a keyless flute as my session partner-of-choice. C-Nat I have a thumbhole for and the cross fingerings work well too, but F-Nat and G# don’t cross finger well on the large holes of my new Windward Prattenesque flute. By that I mean that the notes that come out are not flat enough… And I use those two regularly in our session repertoire. (Comes from getting used to a keyed flute first…)
(“A hole” means the hole which, when open, sounds the A)
So I’ve had to work on my half holing of these two notes and I’d like your opinions of what I do and suggestions for other ways to do it:
G# coming from above, I seem to have it most under control with my normal finger curvature, but extending the gap between my long and ring finger, ie opening the upper side of the A hole, on the side nearer my body.
G# coming from below, the same seems to work well, but here I also have some success with the straightening of my ring finger, so that the side of the A hole nearest my body is open. It does however require preparation, since it is a long way from my normal position on the hole to the point where the hole starts to be opened.
F-Nat - The only one I can get to work at all well is moving the ring finger up the flute towards the right long finger, opening the bottom edge of the F# hole. Works fine from below, but I can’t hit the F coming from above reliably. The distance between my normal finger position on the hole here and where a straightened finger would start to uncover is even further than on G#, so the straightening the finger technique doesn’t work well for me here.
(B-flat I rarely need, but works fine with the cross fingerings anyway. E-flat I am not even going to worry about trying to find…)
It is a big holed flute with slightly ergonomic offsetting and not a particularly long reach and I have quite large hands and use the classical grip on the flute.   (because it works for me!   )
 )
Thanks for any tips or advice.
'bye,
Chris.
