It is funny. I often hear the influence of previous composers when I listen to 19th century music. In Schumann, for example, I often hear the influence of Schubert and Mendelssohn, in Mendelssohn I often hear the influence of Mozart and Beethoven, but when I listen to Grieg, I don't hear anyone specific from his musical past. I hear what future composers might have heard in his music. I hear what might have influenced Debussy to a certain extent, and what might have influenced Gershwin to a great extent.
