Beginning with the early musical short features he created, such as "Silly Symphonies," Walt Disney began a tradition of publishing printed music for all the songs his musical films made popular. His firm eventually formed its own publishing house and then even its own record company to continue this practice. Disney's sheet music was typically simple to learn and play, which made it more appealing to his generally young audiences.
As the very first full-length animated feature, "Snow White and the Seven Dwarfs" was one of the most popular and loved films when it was first released. Re-realeased about every ten years, it has been loved by multiple generations ever since. All of the musical numbers from the film are recognized by Disney fans all over the world.
