if u play note by note, if u kill improvisation (from Bach to Bartok, everyone improvised) if Mozart have stopped saying music is Bach then there are no further innovations, if Bach had stopped music is all renaissance there is no counter-point, if Liszt had stopped music is all Beethoven there is no harmonic innovations, no pianistic performances, but what happened after that... now every one had stopped in classical and still keeps on playing Mozart and beethoven....COPY CATS, the artists ran out of steam, no further innovations, ofcourse there are some modern musicians but they are all banished by classical pundits as nothing more than improvisers and these classical pundits follow still the same score written by this guy bach 200 + years ago. I mean what kinda stupidity is that.
Before the nineteenth century, no one played past music. In Bach's time there were no concerts of Palestrina, in Mozart's time there were no concerts of Bach, and in Beethoven's time there were no concerts of Mozart. It wasn't until the nineteenth century that there was even a concept of "early music" (or earlier music).
I don't think this is true so much... Beethoven as a child was forced to learn Bach and Haydn, and Liszt himself performed the forty eight prelude and fugues for beethoven (allegedly transposing into any key asked by the old man). It's maybe just that the concerts of contemporary music at that time were much more memorable than regurgitating already heard works.
