In my early days as professional flute player I encountered on and off pains in neck- shoulders- hands and back. When playing standing up a long time, my legs got tense and breathing became more difficult . I had learned to brace myself and hold my body still for “ergonomic” purpose, but exactly that was the source of my problems..
Having to “allow” movement without “adding” movement was a bit of a problem. Great players move in a “natural” way. Telling someone to “play freely” doesn’t work : it’s like cueing the goal without the process..
Becoming a teacher of Body Mapping meant a first big step in finding freedom and understanding movement within music making.
