Well - what it says, really.
My two sonatas together added up to just about 44 minutes when I timed them a couple of weeks ago, timing each movement separately and then adding about 2-3 minutes for time between movements etc.
This was, obviously, just about fine - it's LRSM, so 40 minutes +/- 10%.
However, on Wednesday, I had a lesson, in which the teacher slowed a couple of movements down a little - maybe 3, 4 clicks on the metronome. I'm concerned now (though I haven't actually timed, because I haven't yet got the speeds sorted in my head) that it's going to be outside the limit. If it is, it will be by about 1-2 minutes - no more.
What would be the penalty if I overran by a maximum of about 2 minutes?
Ugh. Panicking slightly. Have already cut out all the repeats except one set in the Brahms which I really don't want to get rid of for balance reasons, which only adds another minute, anyway...
