I’m working hard at intonation for the final tenor clef section, particularly the runs where I have to switch the bow after the first note and then gracefully step from Bb down to D.  The shift from G to F is not accurate, so I’m just exhaustively training myself by ear and the tuner. I’m also doing gradual shift exercises so that I can hear the G-F reliably (this is easy in fourth position), then changing one finger at a time until I can do G on 1, F on 4.

In my next post, a music theory question for you. [UPDATE:  I’ll wait until after my performance to worry about my question, and I may see if Quora has it first]
