this is a wonderful dose of reality thread. thanks for starting it. i don't have one at the moment but will post up when i come across one.
Sviatoslav Richterat 15:06, 15:27, 16:04, 17:11, playing Beethoven's Sontata op 2, No 1.
Horowitz was on heavy medication at that point in his life. Poor guy, I don't know why it is that these videos make it online. He's some distance from being my favourite pianist, but he was a true great and out of respect for him I wish the videos from that concert were suppressed.
That was Schumann's Carnaval op.9. yeap, quite serious slips for a pianist of such stature (i know as i studied the work before). However, like what ronde_des_sylphes stated, he was under heavy medication.
At a Rubinstein concert he got completely lost in the start of the development section of the 1st mvmt of Chopin's 2nd piano sonata A complete memory slip. So he simply played a succession of plausible chords for about 10 seconds and picked up the piece successfully a few yards down the pike. I thought his improvising somewhat more amazing than the piece itself. I asked several attendees about it during intermission and no one else had noticed a thing!
I don't have a video of it, but Richter's live "Hammerklavier" on a BBC Legends CD contains fistfuls of wrong notes, especially the fugue. I appreciate the intensity but the wrong notes make it hard to listen to it repeatedly.
I remember a remarkable incident in a performance of the Hammerklavier by Charles Rosen in the 1970s. After making a complete mess of the first two movements he got up from the piano, and from the front of the platform he asked a person in one of the front rows to stop following the performance from their score. He then completed the performance with no further accidents, and he was equally secure in the Diabelli Variations in the second half of the programme.
It is not only by coughing and rattling programs that the audience can be a distraction. Following the score during a performance is perfectly legitimate, and I do not at all mind that some amateurs or students think it worthwhile to keep tabs on my interpretation. It is when they do this in the centre of the first row that attracts my attention, so that I am aware of each page turn. This bothers me only because they rarely have the same edition that I have used, and when the page turn occurs in an unaccustomed place, I momentarily lose concentration, wondering if I have made a slip of memory or speculating on which edition they can be looking at. I have on two occasions stopped a performance between the movements to ask a front-row page turner to look for a more distant seat. I give all these details to make the simple point that the less one is aware of the audience, the greater the chance of a deep immersion in the music that results in a more satisfactory performance.
1:41I remember showing this to my friend and hearing her scream "HE IS HUMAN AFTER ALL!!"
My teacher always tells me not to worry about hitting wrong notes every once in a while. He actually gets pretty mad whenever I get upset for hitting a wrong note."If someone gets mad at you for hitting a wrong note, screw them! You're not a robot, they can listen to a CD or a synthesia!"But that's the second time I've heard Kissin make a mistake! There's a video of him on youtube playing La Campanella hitting EF in stead of just an E in bar 31 lol.
