Thats good. I'm no Polish boy, but still understand Poland's hidden language within Chopin's music. Quite odd, the new generations (just generalizing) (since the 50's) don't even appreciate him.
I've done a number of research and performances of his, and I've found that many of these modern "composers" are just cheap knock-offs of Chopin's music. Listen to the Marche Funerbe (not the Piano Sonata...the indep. piece), and you'll recorganize many of the melodies used in today's music.
Teach your Polish girl about Fred's music. She'll surely appreciate it.
My faves are Bach and Mozart. Chopin is amazing. It is surprising that he only wrote for piano.
He wrote more than for Piano. As a youth he wrote Piano Concerto's, which actually involve an orchestra.
He also wrote many "Songs".
