As a trained guitarist, I'm happy to provide a comprehensive lesson on the subject of the student's choosing. Whether that be a core concept of guitar playing such as chord shapes and extensions, music theory as it applies to playing the guitar, melody and chord progression composition, or just learning a song. Even if a student doesn't necessarily have a set goal in mind when considering booking a lesson, I am 100% certain that I can impart some kind of musical knowledge about the guitar and how its played. My lessons include supplementary material as well. If you book a lesson intending on learning a song, then you will be receiving a chord sheet with the progression and chord charts. If you want to learn a concept like economy picking, I will at least one practice exercise I can provide you with to help reinforce that concept.
