Rt thumb non-existent when going up scales because of lack of pressure. Pulling with elbow to go up, but need to push to get thumb pressure?

Lt thumb is weak when going down.

Both are due to the different arm angles which exert different pressure at different times. It's all physics! Or dynamics of materials movement. Or something.

R thumb is non-existent, which is why the L hand is behind.

Visualizing playing scales at work today may have helped with actual playing of scales? Need to really focus on finger strength when playing for evenness.

Never, ever, tune harp in all ♯'s.

Ha! Judy Loman does not play (flight) at ♩ = 152! Ha, ha, haha, ha!

I take that as permission I do not have to, either.

Worked on right hand, as needed. Right hand is so very sloppy. Don't forget to do nerve stretches.

And relax your jaw, for cripes sake!
