Position your right hand correctly for smooth technique.
Your right thumb goes under the flute, roughly below the F key. It helps support the weight of the flute.
Your right index, middle, and ring fingers rest on the next three keys. Use the pads of your fingertips.
Your right pinky operates the small keys at the end of the flute. Keep it curved and close to the keys.
The flute should balance between your chin, left index finger, and right thumb. You should not need to squeeze tightly.
If your right hand feels tense, put the flute down, shake your hand out, and try again with a lighter touch.
