Of course, one could go into the music theory behind it all, but at a deeper level -- how did they "translate" a painting or scene into a composition? I'm thinking of, say, Ravel Jeux D'Eau. It's really impressive how Ravel conveys the impression of flowing water here. How did they do it?
I suggest your man to ask is Neil Martinez, our own "quantum" on the forum. He is a born impressionist, as his numerous posted improvisations such as "The March to School" and "Attack of the Flies" reveal. If any forum member has any clues about impressionism he does.https://www.pianostreet.com/smf/index.php?topic=31278.msg362838#msg362838https://www.pianostreet.com/smf/index.php?topic=34498.msg400582#msg400582https://www.pianostreet.com/smf/index.php?topic=55190.msg595059#msg595059
