Ok, I changed my embouchure a while ago, and I've recently got back into playing 'proper pieces' now - and I still feel that anything above an F, I naturally tense up at (particularly around the throat area, hence the straining of notes) - and so the sound quality isn't great, and it's just stopping me from getting the notes in the first place.
Me and my teacher have gone over a million things - thinking about tongue position, thinking down when you play up, lying down on the floor!, jumping before you play a high note to relax muscles!, lots and lots of breathing exercises, concentrating the tension at the abdominal muscles rather than the throat - the list goes on...
and basically we can't find a way to stop me from getting tense - I do get really upset about this, and I'm to be honest quite hard on myself about it, and I don't know how to get rid of these negative thoughts because obviously these are probably affecting my playing also...
Does anyone have any suggestions at all? I'm really desperate, and for someone who's been used to playing up to top Cs and beyond no problem, it's taken a real hit to my confidence - I have places to study music at uni from sept this year, and I'm scared that I'm not going to overcome this before then, because I want to become involved in orchestras and stuff...
please help!
