> I think many concert pianists will live their entire life without a single noticeable mistake at a live performance. I don't know what concerts you've gone to, but to the ones I've gone to, I've definitely heard mistakes from the pianists sometimes and a quick search on Google reveals it's a lot more common that you think, especially since you think that these masters (because I do think they are masters, don't get me wrong) never ever make any mistakes in their entire life. And no, playing the wrong note is not the only mistake you can make as a pianist. Most mistakes are simple mistakes that can happen to anyone. The reason you haven't noticed them so far, is that most professionals are very good at hiding their mistakes on the fly and not draw attention to it, so you think everything is well. But if you have a keen ear and you're familiar with the piece they are playing, you'll definitively notice some mistakes sometimes. It's not the end of the world though, and I personally think it brings a more personal touch to the performance.
