In “Steamboat Willie”, the sound is used to emphasize gags and jokes. The introductory scene is very sound-heavy, as Mickey whistling is in tune with the rest of the music and so is the wheel of the steamboat. Both of the sound’s play off each other to create a catchy tune while still being completely relevant to the story. Additionally, Mickey’s sounds are very light and upbeat compared to Pete’s sounds which are a little more menacing compared to Mickey. Music is one of the most important roles in this movie because it is used to portray the mood of the scene through what is happening around them.
