To illustrate the point, I can play Bach Inevntion in my sleep when I am playing at home but if I am playing and someone is watching I liteally won't be able to go through a measure of music without making any mistake. I guess It's a performance fear issue.. a psychosomatic reaction.. because the sensation is not real but imagined. It was so weird how this sensation came suddenly as I was taking the bus to play.. I had not had this feeling since the last time I played... which was couple of month ago.
javacisnotrecognized,
I am not sure what you meant by your last comment... I am not sure how i gave the impression that tension was the solution.. what i meant was that I get this strange sensation involuntarily and it seem to happen only during performance, and whatever adjustments I made in practice (with or without teacher)has not helped me so far...where would I be looking for solution?
loonbohol,
Yea, having awareness of your shoulders and your arm helps playing.. the problem right now is not so much about not being able to use them.. but its about how my whole arm seem to freeze up when I perform.. and only when I perform.. it never happens in practice.
