Rach Prelude Piano Switch?

[pianist7]

It's very odd: the other day I was playing the Rach C# minor prelude on a different piano (actually it was an digital keyboard) and played the Agitato section with almost no mistakes. On my normal piano, I keep making mistakes all the time. Could someone please explain this in some more depth?

One possibility is that your regular instrument is out of regulation.

That is strange. The other way around would make more sense.

Stevebob might be right.

well but couldn't it be because the keys on a digital keyboard are much easier to press that on a real piano? so some things are easier to play (because your fingers can move faster or something).
I dont know...  or sometimes it's just like when you don't expect that you could play something really well and you just try it (without worrying about it) you just don't make mistakes, but then when you are trying really hard not to make mistakes then you make really a lot of them.

My theory is that your hands and body posture had ingrained very subtle misalignments on your regular piano. On the other hand you had learned the music very well. When you went to a new piano, you were probably seated a little differently and the keyboard felt a little different. The suble misalignments that threw you off on the old piano disappeared and the major, correct, movements and the music that you learned correctly took over.

This happens to me all the time when I leave a piece for a few weeks that I had learned very well but there was always certain places that gave me trouble. A lot of times when I come back to the piece, the troublesome places aren't nearly as bad - my theory is that the subtle things going wrong faded away and the strongly memorized stuff took over. Doesn't happen nearly all the time, but it has happened enough for me to remember it.

Well usually it's not a help for me either, especially if I learn to play something well on the real piano and then have to play on a digital keyboard (like on my recital  ) it's really weird. But if i only just start learning something then there are some things that seem kinda easier to play on a keyboard first..... but maybe that's just because my fingers are not strong enough yet or something or because I don't play piano for a very long time yet. (Until february I only had a digital keyboard at home so sometimes I learned to play something really well on my keyboard but then at my piano lesson it was a lot harder to play on a real piano).
