On both the Suzuki and the Schroeder, I need to keep my left hand in a shape and minimize finger movement. Chords need to be tuned. This is new to me, although I do understand what it means to tune a double stop, so perhaps I can generalize. Once the chords are tuned, this should help the triplets in the Suzuki (Witches’ Dance).
I realize nobody reads these anymore, but I found it keep writing these for my own benefit. It is helpful to review my notes on past pieces to see what I worked on and what progress has been made.
