Q.1 Watch the clip attached above this and discuss how the use of sound enhances the clip.  How does the sound help to tell the story?  What would this piece of film be missing if there was no sound?  Your answer should be at least 100 words.

Q.2 Choose a clip of your own that you feel uses sound in an extremely effective way.  Maybe it's a clip where the song moves you to tears, or maybe the sound is terrifying, or maybe it is heart-wrenching. Music is a direct line to our emotions in a way that almost no other art form can be.  Find that clip and explain why you picked it.  Your description should be 75-100 words.
