Introduction: I have been singing and playing guitar since I was 12 years old. I have shared stages and rubbed elbows with some very talented folks.
I love the guitar but as with any undertaking, I can show you and demonstrate but it will be up to you as to how good you become. Instruction is only a quarter of what you need the rest 25% depends on your ability to absorb the lesson and practice is the other 50% of the equation so you do absorb it whether or not you understood it in my presence.
We start with basics like octaves and chords, and there is no need to read music to play guitar. I can read music but to learn to play the guitar, we use tablature, and I will teach you how to read it and understand it if you don't know already. This would be guitar 101 basics which will give you all the tools you need to advance, but I'll leave guitar theory to the music professors!
