Acoustic and Electric Guitars are available to use for your lesson
Mick's Amp and Pedalboard - Student Amp and Pedals - Bass Amp
My approach with a young beginning student is to use a method book like "Fast Track-Book 1". I feel that a method book helps to give some structure to the lessons. During the course of the lessons I give out supplemental sheets to further embellish the basic exercises/melodies presented in the book. Here are some examples:
I will also introduce chords at a graduated pace - going from simpler versions to more "standard" versions. As the student is progressing I will introduce playing the exercises from the book in various positions(using fretboard diagrams and tabs) and in different keys. Here are some exercises/songs from Book 1 played in higher positions:
For a teen-age student I might tweak my approach somewhat because typically their hands are bigger and are able to execute movements on the fingerboard that would be difficult or nearly impossible for a younger student with smaller hands. As the student progresses, I would start to introduce some other topics such as:improvisation (using my Jam CD series) & playing Classic Rock songs from my Acoustic and Electric Playlists depending on their inclination and instrument.
For an adult student I would use a much looser approach, realizing that most adults have very busy lives with a limited amount of time to spend with their instrument. So we might jump around to various topics and songs to keep things moving along and not allow anything to get too tedious.
