However, we can gather some clues:
* His Films: Disney was a huge proponent of music in his films. He understood its power to evoke emotion and enhance storytelling. He frequently worked with iconic composers like Leigh Harline, Frank Churchill, and Oliver Wallace. Songs like "When You Wish Upon a Star," "Zip-a-Dee-Doo-Dah," and "Chim Chim Cher-ee" became massive hits and reflect the kind of music he favored for his animated films.
* His Love for Classical Music: Disney had a deep appreciation for classical music. He even commissioned a symphony from Dimitri Tiomkin for "Fantasia."
