The two images below show an exercise set I was contemplating practicing. The fingering is my own and would focus a lot on changing position with the fifth finger for the part playing eighth-notes. I though the fingering could be used in all keys.
This there anything about this exercise that would be harmful or counter-productive? Could it risk tendon strain, or is it contrary to standard piano methods? Am I overlooking a more typical fingering.
I can't find a good method book with these kinds of running eighth-note figures in all keys. This exercise is my own attempt to make one. But, I don't want to use it if it's bad technique.
