Playing 3rd Octave B to C

[circlenaut]

I guess a little background first. I played the flute as a child from the 3rd to 5th grade but quit because of bullying. I am now 26 and picked it up again about 4 months ago. I own a Pearl 665RBE1RB. When ever I play B to C in the third octave the entire flute slips forward about 25% of the time when I try to reach for the gizmo key. When I don't reach for the key this never happens but C3 sounds "off" or I have a hard time getting the note to come out at all. Any tips?

I think you are describing B3 to C4. C4 uses the gizmo. You may have the headjoint rolled out too far or your hand position is such that the flute is not well balanced. Try refining your hand position for a better balance of the flute.

Also, you may be tending to push the gizmo key AWAY from you rather than pressing down. That would cause the flute to roll forward.

Hello pied_piper I think you're right I've been pushing away on the key especially when going fast. I'll practice alternating B to C and back then slowly add Bb-B-C then A-Bb-B-C. Thanks!
