Reply To: Weird problem with flute
If there is a problem with the key next to her right hand pointer finger, this could explain both situations. Does the instrument have a split-E mechanism? If it is not working properly, that could be a problem.
Has the student previously played high E with no problem? That note is one of the pickiest notes on the instrument in terms of speaking. It will over-blow or sound an A above the staff if the airstream is not angled correctly and the air is not the correct speed.
