pianoloverus If the tempo or dynamic changes you mention are indicated in the score, then doing them would be reasonable. Even then, since this is basically a pop tune, it's much more open to deviations from the score compared to a classical piece.
I am not sure, if you aware of it, but back in the era of classical music, there were no audio recordings. Composers had to write everything into the score; it was a necessity. This need vanished with the upcoming of audio recordings more and more, because listening to the orignial gives you so much more information than you would be ever able to write down.
Anyway, I would not count this one as pop music by any means. I would classify it as new-age music, similar to Einaudi or French. Or maybe as a radio station did: as "modern-classical".
pianoloverus Except for the obvious ritard at the very end of the part you posted which makes sense, the interpretation is simply a matter of personal choice and it's not necessary to copy one interpretation.
You are right, it is not necessary to copy. But OP did at 1:26 very well, so I assume he intended to copy the original interpretation.
pianoloverus By the way, the OP does slow down slightly at the two minute although I'm not sure if it was an intentional choice or because the music gets more difficult technically.
No, he didn't. If he did, I wouldn't have mentioned it. I know the original interpretation so well that the difference was like seeing flashing lights.
Anyway, I don't think this part was an extra difficult part within this piece. All in all OP played very well and this missing rubato was a tiny critique on a very high level.
