We carried on with the development of the 4 chord song. We decided to add harmonies to the songs in our piece and tighten them up. We developed the harmonies by ear on the piano for and created the harmonies for the songs "Don't Matter" by Akon and "I'm Yours" by Jason Mraz.

Also, we looked at changing the way we would present the piece. At first, we were very keen on performing the piece accompanied to a piano. However, we felt that we would be copying the original performance by Axis of Awesome. We made the performance fully acapella by including stamps and clicks instead of the piano. However, I struggled on a lot of occasions to cope with the timing and pitch of the notes I was trying to hit. I felt that I relied heavily on the piano to help me pitch my notes. Once we took the piano out, I couldn't pitch my notes when singing or when trying to sing harmonies.
