Sound analysis

 The clip below is from dumber and dumber.

In the clip below the diegetic sound comes from the characters and their dialogue. It can also be seen through the two main characters repeated use of annoying phrases and noises. Diegetic audio being audio only the characters in the scene can hear.

The sound bridge can be seen when the car stops to pick other people up and the guitar starts playing a few seconds before the camera shifts to reveal the people in the back of the car singing along to the song.

The music is a bizarre focal point because it is not instrumental or digital but instead it is created by the two main characters as they sing along in harmony. The dialogue can be used to represent the two main characters personalities and their relationship as through the harmonic singing and constant noises which match each others it becomes evident that they are close friends. The music that the characters make is parallel because it perfectly represents their mental state and their characters.
