Fauré took up many of Chopin's forms, including Ballade, Impromptu, Nocturne, Prélude, and Barcarolle.Scriabin also of course.
john field? never thought about faure, but that makes sense too.
I know Field influenced Chopin through his nocturnes but i'm not familiar with any of his other works.When your pairing the composers up like that - Mozart Haydn, Bach Handel - isn't Chopin generally paired up with Liszt (if you want to make a very broad comparison)? They both wrote bulk music for the piano, they're both very much romantics, they knew eachother, they both have popular appeal (I hate myelf for mentioning that but the only 2 composers my family know/like are these 2 based on the Liszt tarantella and the polish polonaise).
Scriabin used Chopin as a muse, but his music isn't really very Chopin-like. I suppose some of the early short pieces are closer to Chopin than most other composers' music, though.
