Since you have more than one flute, I'd assume you've been playing for a while? For what it's worth, when I started out, I took me something like a year and a half to develop a flute hold hold that felt comfortable, steady, and instinctive. When I got a heavier keyed flute, I had a good basic hold but it took couple more months to really get comfortable. Now I just pick it up and the hold is automatic and comfortable... which is a good thing, because I have so many other things that need work in my playing!Lsu wrote:Rolling the head joint in does indeed help, but even at an extreme angle, it feels like if could slip out at any moment (and does eventually). Maybe I just need more practice with it.
Anyway, keep practicing and trying different things, because it may just take more time to get the various muscles trained for a good flute hold.
