Besides Beethoven's wonderful music, I learned that he always had the work as a whole in view when he was composing, something I find important to remember. Quite funny the description of his apartment: three grand pianos on the floor without legs, a chair with 3 legs, leftovers from a snack, on a standing desk the draft of a new opus, half-empty bottles,... but this chaos was juxtaposed with an utmost methodical approach in his composing work. I also like the story that for his 7th symphony he had created a new musical annotation for a horn section, not f for forte, not ff for fortissimo, but fff for super loud, which probably is a good description of my color palette as well.
