For Irish flutes, how much do you adjust your embouchure and air speed when making small changes in the register, such as G4 to E4/D4?
I've been playing flute for ~9 months on a delrin flute and have recently upgraded to a wooden flute. I absolutely love the sound of it, but I'm really struggling with intonation. On my delrin flute, I am able to go through the first and second octaves without many intonation issues (i.e. +/- 10 cents), but with this flute I find that my low D and E are often 20 cents sharp and my low G is 20-25 cents flat (F# being slightly less flat). I've checked the cork and adjusted the tuning slide, but without much improvement. Anyway, I was wondering if I perhaps underestimated the amount of adjustment that I would need to make for these notes. While my delrin flute is able to accommodate this interval without too much adjustment, I feel like on this flute I need to make drastic changes to get the respective notes within decently intonated. I apologize if I haven't given sufficient details, and I would greatly appreciate any thoughts!
