Being a extra singer

Seeing as I didn't feature much in the video I thought i'd make a tutorial about being a extra/back-up singer. I've found example of current videos where the backing singers help the lead singer by playing instruments, humming along and emphasizing sounds sometimes. Back up singers are usually just important as the main band member.

These photos represent how the back up singers are helping the lead singer. They might be in the same shot while singing to reinforce the vocals. Sometimes they will be on camera alone to show that there are others singing.

Mumford and Sons - Little Lion Man
In this video there are 3 men who sing along with the main singer. They way the men are displayed it seems like they are very well known because they are all shown so much. The main singer will always be shown more.
