Hi everybody,
I've been reading quite a lot on the online piano forums lately and it seems to be a very popular opinion that "you play as you practice", so if you practice with a lot of errors, of course you're going to do the same mistakes during actual performances.
Now, what is rather interesting (and despairing) to me is the fact that, basically, I seem to be unable to play a piece, even simple ones, without making some kind of mistake: be it an A instead of G, be it just a slight delay or acceleration in the tempo, be it just an short uneven passage in a piece, 95% of the time I simply cannot produce a perfect performance. Sometimes I'm at the last bar of a piece and I haven't done any errors, I'm fairly sure that everything will go smoothly and BAM! target missed on the very last note. Heck, I'm sure I wouldn't even be able to play Twinkle Twinkle Little Star 10 times in a row if I tried.
And I'm not talking about always the same errors repeated again and again at every piano session. Those can be of course overcome by concentrating on them, repeating the problematic bit many times in a slow and controlled fashion.
I'm talking here about parts that I had always played perfectly, that suddenly, one day, fall apart by surprise, and possibly the day after come back ok once again.
But that single day, my fingers just slip on that "mastered" bar of some piece, and so I start from that bar again, sure that everything will go alright as it always has, and instead I just can't seem to make it and I'm like "what the f is happening?? I've always played this without any problem at all!"
It might take me hours of repetition to finally be able to play that part at speed.
Also, when practicing a complete piece, slow practice is often advocated, but it happens quite often that more instead of less errors happen when going much slower than usual, possibly due to the higher difficulty of keeping concentration on very slow tempos and on the lesser reliance on muscle memory.
Does this kind of stuff happen to you? How do you handle it? Do you just ignore the occasional slip and go on playing the rest of the piece like nothing happened or do you stubbornly start repeating the measure that is giving you trouble (or even the whole piece) until it's correct? How is it possible to avoid such unexpected slips if, by definition, they are unexpected? Is it simply a matter of needing to wait and practice for several more years before achieving a truly perfect performance? Or do you think that some people simply need to accept the fact that their playing will always have the occasional flaw and only on rare occasions will be able to perform without any mistakes?
Thanks for sharing your experience.
