Everyone seems to be drawing from composers of the Baroque and/or classical periods. I guess a better way to ask the question is to ask which is the best composer of their time or genre.

I would say Bach, but I don't particularly care for baroque period music. My personal favorite period of classical music is romantic. Of the romantic composers, Chopin is by far my favorite. That's mostly because I'm speaking in terms of Solo piano music morso than chamber or symphonic music, of which I don't listen to much.

Piano...Chopin I feel is the greatest. I don't know much about symphonic composers..
