Cumulative Acts Proposal

I've always enjoyed music and singing.  So for my cumulative acts I have decided to sing a song daily until the end of the project.  At the end of the project I plan to overlap all of the pieces of audio together and create a chorus effect.  It will be interesting to see how close I am to singing the same piece the same way each time, or how I change things up a bit based on how I think I need to improve.  Each day I will use either audacity or one of my softwares at home to do the recording and combine the pieces at the end.  The process should be shown through the amount of sync or lack of sync in the final project.
