Theory is very important to UNDERSTAND how to play and create wonderful music. Without really understanding theory, it makes the performing of any musical piece difficult. So to help you, the student, I have added some theory files, which are only beginner files to give you something to start with. Theory is the head knowledge and without it the heart knowledge doesn't go very far. It should not be something that is seen as a dreaded thing but something that is enjoyable and any age can learn and understand.
