Sounds

Sounds in opening sequences.

If there is no sounds whatsoever, it builds up tension but, it also allows the audience to get distracted, so it is always a good choice to include some sounds, even if just the natural sounds of the setting that you are filming at or an actual song. If you chose to use a song I think it adds to the genre of the film, but, it also makes you as a director make a personal decision to a song choice, so it would have personal preference behind the song choice, and not everyone shares the same choice in music taste so music can put a genre barrier on it.
 For my film, I think it's going to be difficult to find an already made song to use, as we wont really be able to get permission from the artist, so we may have to just use the natural surrounding sounds, or get a friend with musical talent to create something for the two minute opening scene.
Because our opening scene we want to show a girl getting drunk having a nice night and then waking up somewhere else on her own and that's what I want to end the opening at, I think there should be a voice over perhaps of the two girls laughing at the beginning and then the sounds fading into the sound of the girl coughing, retching and throwing up and other disgusting noises the drunk make.
