“Steamboat Willie” is notable not just for having Mickey Mouse’s premiere, but also for employing fully synced sound, which was innovative at the time. The film’s sound is employed to accentuate the action and enhance the film’s comic effect. For example, in the moment where Mickey is piloting the steamboat, the sound of the engine and the slapping of water against the boat are timed with the movement of the boat, giving the spectator a more immersive experience. Similarly, as Mickey utilizes various things on the boat as musical instruments, the sound of each object is timed with his movements, making the song more engaging and interesting.
