When it comes to learning a skill like guitar this is best achieved using a clear structured plan for a very simple reason. There are many different styles of music and of course many ways to play a guitar but the fundamentals are much the same. A clear structured plan is a way of learning that will reliably bring about a result and ensure the fundamentals are being developed. For beginners this is the best way to learn because having no plan is risky. Very risky. By starting with a clear structured plan and reaching lets say an early intermediate level you can then begin to focus on your favorite style. Often when experienced students enquire about lessons with me they are motivated by frustration. They feel like they are not getting anywhere. A structured method of learning solves this problem. If you are learning guitar without a plan I would recommend seeking one out. If you are a beginner it is best to start with a recognised method of learning. At the very least divide your time between a structured method of learning guitar and what I like to call random learning.
