My top composer would have to be Chopin. Chopin’s melodies are expressive and innovative. His music almost gives off a darker vibe, like something you would play on a stormy night.
Mozart,schubert,brahms,tchaikovsky are the order of most liked musician. Mozart had a great voice and melodies was great. Most of others are also great to hear.
I think Bach stands separately. He was an organ player at the Leipzig cathedral (been there once) and his music is a kind of special one for dedicated instrument. Very monumental neveretheless.
