Step one: Learn how to play guitar: Justin Guitar is a fine and free place to start learning chords and the basic skills you'll need to be able to play guitar — from there, it's up to you, but once you know the basics, just looking up tabs for your favorite songs and learning them on your own is how many young guitar players get their start (plus it's an excellent party trick).

Step two: A delightful free voice lesson from Berklee College Of Music.

Step three: Have you always thought you had an inner TSwift? Berklee College of Music offers an Introduction to Songwriting course completely for free online. The course is six weeks long, and by the end of the lesson you'll have at least one completed song.
