Yes, I've experienced it.
I probably would tomorrow if I suddenly found myself in Prince's band at Giants Stadium.
But at least I would know what was going on and how to remedy it.
I was personally taught for years.
I went to music school for four years but bunked off a lot of my drum set tuition.
My teacher was a jazzman through and through. He had no time for my rockin' ways.
In short we didn't get along.
The biggest thing he taught me was relaxation though.
I've thanked him ever since. You really can't play if you tighten up.
First thing he did was identify it as a problem with me.
Secondly he kept on at me, lesson after lesson, every time I played for him and hunched a shoulder or screwed up my face.
Eventually I could feel my body going into tension - and that was one awesome skill he taught me that's paid off my entire life since.
