It takes 5 minutes to tune when the top half is out of tune.

Taking a stretch break seems to help, 1.5 hours today.

I have 2.5 pages solidly memorized, last 1.5 should be pretty easy, a few spots need work.

ETA: I just realized I played for 1.5 hours today! 1.5 hours and my elbow didn't bother me at all!
