One of the most amazing things about music is that it has a profound effect on the listener’s emotions. In an instant music can make the listener sad, happy, joyful, content, etc. The soundtracks in a movie are meant to manipulate the viewer’s emotions. I think that a great soundtrack can make or break a movie. The music helps build an emotional connection with the characters. One of the best examples of this I have ever seen is in the movie UP during the scene that shows a couple growing old together.

In under five minutes one goes through the emotions of joy, anticipation, dissapointment, grief, and sadness. The music is a big reason. The music fits with each scene perfectly. During sad scence it slows down. When things start to look happier the tempo picks up. The music has a thicker texture when it is a happier scene. During the sad scene the texture is very simple and quiet. All of this combines together to make a very emotional scene.
