What is the hardest "good" and mostly tonal piece with only a few notes?Hamelin´s triple etude based on Chopin gets my vote.
What do you call "with only a few notes" ? Hamelin's triple etude has, hem, a bunch of notes IMHO.
Shouldn't playing the hardest piece be considered the most difficult achivement possible on the piano? If person x can play the msot difficult piece in the world then one should assume that this person have done the most difficult thing possible on the piano. Sadly this is not the case. It is pointless to disscuss what is the most difficult piece on the piano. Isn't more interesting from a purely pianistic perspective to try to find out what is the most impressive pianistic feat one can do?"Playing" a piece doesn't reveal anything about you. Just think of the Chopin etudes for instance. What do we learn about Gavrilov after hearing him play the Chopin etudes? And what do we learn about Rusnak after hearing him play the same pieces?Well that Gavrilov has a world-class technic and that Rusnak doesn't. "Playing" a piece doesn't tell anything about your technic, it is how you do it that matters.Another example is the Opus Clavicembalisticum. Often regarded as one of the most difficult pieces in the repertoire. Madge has played this piece. So one would just assume he has one of the greatest technics ever to "play" such a difficult piece. But this is also wrong. Because when one listens to Powell play this piece, one realises that while Madge may have "played" the piece there are technical flaws EVERYWHERE. Still Madge can say that he has "played" the piece. But Powell's achivement is FAR greater, even though they have played the same piece. One could assume that if two people play the same piece they have done the exact same achivement, but this is NOT the case.
