Making Progress

I am learning how to play a guitar. It is coming to me slowly but surely. Here is a picture of me on the guitar. My dad bought this nylon string guitar in Tucson at the Chicago Music store. I also have a steel string guitar that my Grandpa gave me. The nylon is strung righty but since I am lefty, I play it "upside down". What is your advice on that choice?

In Math Class I learned about functions and how to write codes using a graph. If you'd like to figure out what I've written above, download the attached key.

No clues. I know you can do it!
