Charles Rosen Quote
The opposition between structure and sonority in music is almost as misleading as that between line and color in the visual arts. Baudelaire insisted, correctly, that Delacroix was one of the three greatest draftsmen of the century, and emphasized his mastery of line. In the same way, a study of Chopin demonstrates the intimate relation between line and color in music.
