40 min
Warmup 5 min playing through Popper #9 slowly, focusing on the short note leading into the slur.

Then 35 min trying to figure out the Vc1 part to Offenbach Adagio for cello quartet. I think I'll be OK except for a very high treble clef part in the middle.

Took a short break at 25 min to check all the email coming in, but stopped the timer while I wasn't practicing.
