Tlc "Unpretty" http://www.youtube.com/watch?v=YcgM_cFyDuA

Robbie Williams" Strong" http://www.youtube.com/watch?v=oHMibYhlL-0

We would like the audio to create emotion to the audience when watching our project. In order to do this we need to make sure that we choose the right song. from the rythm of the beat; our piece is about insecurities this is an emotional subject,therefor we need a slow beat as we want a positive outcome the beat should become more uptempo towards the end. The lyrics need to relate to the theme, this will help to create an atmosphere towards the audience. if we chose a fast uptempo beat all the way through it wouldn't have as greater impact on the audience, and we wouldn't be getting the emotions that we intend to create.
