Doris Mortman said this quote

Beethoven introduced us to anger. Haydn taught us capriciousness, Rachmaninoff melancholy. Wagner was demonic. Bach was pious. Schumann was mad, and because his genius was able to record his fight for sanity, we heard what isolation and the edge of lunacy sounded like. Liszt was lusty and vigorous and insisted that we confront his overwhelming sexuality as well as our own. Chopin was a poet, and without him we never would have understood what night was, what perfume was, what romance was.
