Music in film

Where does the sound in film come from? http://filmsound.org/terminology/diegetic.htm

Music plays a huge part in our understanding of a scene in a film and how we react emotionally. There are different types of sound in film:

Score - specifically composed music for the film, often matching up with the onscreen action (ie Harry Potter)
Soundtrack - pre-existing music that is chosen to use in the film, accompanying scenes (ie Pulp Fiction)






TASK:
Open two windows and go to YouTube in both. On the first window, find a clip from a film you really like. What is the music like? How does it affect the scene? 

Then find song in other window (or a movie scene with no dialogue). Mute the clip in the first window and what the scene now with the music playing from the second window.

Find a few examples of this and post them on your blog.
