“So much of the research on musical expertise has looked for accomplishment in the wrong place, in the facility of the fingers rather than the expressiveness of emotion.”

quote of Paul Klee from the text Exact experiments in the realm of art, 1928; as quoted in 'Klee & Kandinsky', 2015 exhibition text, Lenbachhaus und Kunstbau Munich, 2015-2016 https://www.zpk.org/en/exhibitions/review_0/2015/klee-kandinsky-969.html

"Introduction" of Four Screenplays (1960). <!-- Simon & Schuster -->
Context: When we experience a film, we consciously prime ourselves for illusion. Putting aside will and intellect, we make way for it in our imagination. The sequence of pictures plays directly on our feelings. Music works in the same fashion; I would say that there is no art form that has so much in common with film as music. Both affect our emotions directly, not via the intellect. And film is mainly rhythm; it is inhalation and exhalation in continuous sequence. Ever since childhood, music has been my great source of recreation and stimulation, and I often experience a film or play musically.
