Bach Fughetta (I think this is from a Cellobrations volume.)
Worked out tricky fingerings, bariolage with extensions. Also turned out to be a good warmup for thumb position, as one line is best played with thumb on 4th pos'n and hand in WHW shape on both A and D strings.

Main goal for today's practice session is to prevent me from embarassing myself (again) at quartet rehearsal tonight!
