In Chopin's Case
2005.07.10 1:20

In the case of Chopin, the problem is so severe. No pianist including some of highest virtuoso is unable to play the piano fully expressing what Chopin intended to express.
But even the problem is more severe. Chopin's music is located deeper than what he expressed in various signs and notes, so his expression cannot meet his intended music.
His music is so perfect that anyone including any virtuoso and he himself cannot express. To feel his music in our mind. That is the only way left for us.
