This could be a shock to any performer and the situation grew worse as there was no piano available and the recital was called off.
but for the artist, I'm sure they're not so funny in the moment.
I heard a story about a pianist who didn't check the piano out ahead of time. He sat down, hit the first chord, and heard nothing. None of the keys produced sound. The guts of the piano had been taken out for repairs by the technician.
Once the composers at my uni decided they wanted to hold their term concert in a cozy seminar room usually used for grad colloquiums and such activities. There is a Steinway with two pedals there. All was going fine with the solo piano pieces and such until they came to the clarinet + piano piece. The piano was in tune with itself but 1/4 tone flat than normal. Made for some interesting music.
That may be apocryphal. If the tech had taken the action out, the keys would have gone too!I had to accompany a singer in a venue where the piano was an unrestored 1841 Pleyel. All very nice as far as history goes, and plenty appropriate for the mostly 19th century programme, but unfortunately the dear old thing was about a whole tone flat. This made some of the songs unfeasible for the singer so I had to transpose some of them. I don't mind transposing, but some of them were already transposed as they were printed in mezzo keys and the singer was a soprano. This meant I was re-transposing them and, since I have perfect pitch, I was reading one key, playing another and hearing a third. I really felt I had earned my fee at that one.
Surely the clarinettist would've been able to fix that.If it was a quarter tone flat, he just would've had to make the instrument longer, and it would've been considerably more in tune.
Once I was scheduled to play the Waldstein Sonata for a musical society. Preceding me was a string quartet. When they finished, I was called and after some applause I sat down at the grand piano. The keyboard lid was closed and looked a little unusual. When I opened the lid, to my horror, there appeared a double keyboard, like that on an organ. I started playing, but couldn't concentrate - I kept looking at the keys immediately above the ones I was playing. It made my head spin. It wasn't long before I got completely lost. I apologized, explained that I coldn't play this piano, and left. Very embarrassing..........
OMFG! What the hell was that piano? Did you actually discover what it was lol? Did it sound good if you could forget the other keyboard?
