I hadn’t made much progress this past week, and let Dan know up front. Surprisingly, we had enough to work on with the two line Kummer #21 piece. We worked through shifting and making my hand open up. Spent quite a long time on double stops and tuning. Ultimately the question is simply “Do you like it?” Another point on LH was opposite motion. I need to adjust my arm downward to adjust my finger upward.
On the right hand, we worked though how to practice. If I practice one bar at a time, it will keep my bow moving more freely.
When moving near the tip, I’m going to need that thumb, so be aware of the consequences. But otherwise, if the music says it’s OK, stay nearer the middle of the bow where the strings can help my fingers balance.
