Who wrote the most classic music in the 19th century?

Answer 1

the guy with hand cramps wrote the most ... the copyist!!!!

Answer 2

There are many different question you could ask - who wrote the greatest number of pieces, who wrote the longest amount of music (in total duration), who wrote more physical notes than any other...

I'm not sure if you'd actually learn anything from knowing the answers to those. But Liszt definitely wrote a lot more music than Brahms or Beethoven did, and possibly even more than Schubert - Wikipedia lists 999 pieces.

Answer 3

"The most classic"?
Hm...
"In the 19th century"?
Hm...
Beethoven. :-)

Okay, if you would like a "romantic composer" (although many claim Beethoven to be that, too), then, no question, it was Johannes BRAHMS.

EDIT:
Ooooops, reading the answers of others, I realized, that I misunderstood your question.
Sorry.
I understood that as you were curious about that who wrote the most classical music in that century. That was the reason why I advised eventually Brahms, for Wagner told that he was a champion of the old forms, and he (I mean Wagner) was right.
Sorry, once more. I was not wholly awakened so early in the morning. :-)

Answer 4

The ones that wrote the most were not necessarily the best. However Schubert's opus numbers in the Deutsche catalogue reach well over 900 (the 'Great' C major symphony, his 9th, is D944, for example). Most of these works are short songs, however (but none the worse for that).
