Let me start by saying that this information may come later, and if so, please point me in the right direction.
So far through all stages of the course I have viewed, all exercises begin on low C. When away from the course material and actually playing music, starting on higher notes becomes difficult. I find that setting the corners for a note above low C leads to tension. Starting on low C, moving up to the music start note, remembering the shape, and then trying the higher note alone has not helped.
Any advice on setting the shape for higher notes?
