I'm currently working on Couf's Introduction, Dance, and Furioso, and there's a part in the Dance movement where you switch from Middle F (Left Hand+ 1 finger+ octave key) to High F(All 3 palm keys and the right hand side key). I'm having trouble on getting the high F to play after switching suddenly. I'm making sure not to tighten up my embouchre and to keep the air stream fast, but I'm still having troubles doing the quick switch. Should I find a different fingering, or just repeat middle to high F over and over again?
