this ever happen to you?

so you're practicing a peice before you go to bed.  You got it down to a good degree, but you cant play the whole thing without making like 5 mistakes.  Then you go to bed, and wake up, and you can play it flawlessly!  This just happened to me today, and im quite happy

That's called Post Practice Improvement (PPI). Search this forum for it, and you'll find that it is being talked about extensively.

In any case, now you know that it may not make any sense to work out all those mistakes in a practice session, because often enough, poof - they disappear over night!

this is also the reason why it's important that the last rendition you do play is perfect, even if played very slowly.  so never end a practice session by whipping off a flast but horribly flubbed version of your piece, end the session on a flawless note.

Read C Chang's book...

It talks about the PPI and also other major issues of Piano Practice. As a matter of fact, my piano teacher is taking a look at it now.

I've started the Barber Sonata, and this PPI stuff has been happening to me quite strongly. Had some rather unsure playing in one part, but today I could play it perfectly! Also, I went on vacation after having studied Alborada del Gracioso, came back and it was better by tons!

PPI is nothing more than just not knowing that you know. Often in piano when we see something our mistakes we always should try to understand and see why we are doing it, what are we missing or adding lol. If we don't consciously do it often this mysterious PPI kicks in, you solve it in your subconsious, the mind some how bends through the problem without you consciously thinking of it. In the end you have to understand what you are doing if you are to remember it long term. I guess use the PPI effect to make the conscious understanding of what you are doing.

Yes, as a matter of fact, I decided to see how much I could recollect of the fan imp, and I managed to do the first part of the chromatic scale in the RH on the bottom of the second page memorized; normally I'd mess up but the PPI is helping me.

ppi is inevitable

but it doesnt mean you should practice any less
