We’re happy to tailor the lessons to do exactly what you would like to do. It all depends on the type of guitarist you want to be. It’s not initially important to be able to read music notation, but then if you don’t read TAB either it becomes rather hard to remember your whole repertoire. However, some guitarists have a strong ear which is an excellent way to play.
It’s about balancing the amount of music theory that you need – it’s important to have a good grasp of what you’re doing and why it works as you’re playing, but some tutors go too far with this.
