During April, I focused on Music.  I wasn't able to play every day, but I consider the effort to have been remarkably sucessful.

What went well:
 - The challenge was fun!
 - I was able to get Jessica involved
 - There was a clear sense of progression

What I could have done better:
 - Incorporated violin
 - Written Jessica a song

At the beginning of the month, I was struggling by with ~70% on rockband pro guitar on easy mode.  By the end, I was playing through many songs confidently on medium, earning 80% or more.  I think I could start tackling some songs on hard, although I haven't ventured there.
