In addition to revolutionizing animation, Walt Disney soon realized that music could become a key element in the success of his films. Thus, from "Snow White and the 7 Dwarfs" in 1938, he gave a central place to the songs before calling on his songwriters from pop to write original melodies in "Mary Poppins" in 1964. Since then, Disney Studios have worked with many singers, from Louis Prima to "The Book of the Jungle" in Anais Delva for "The Snow Queen" by Céline Dion for "Beauty and the Beast". The paper recounts Walt Disney's musical universe and history, with testimonies from artists such as Gwen Stefani, Jenifer, Melody Gardot or Ne-Yo.
