This supplement works with either edition of the Mastering the Guitar: Class Method, Level 1 to help give students a conceptual look at the guitar and a sense of familiarity with the instrument. It includes twelve exercises and quizzes which coincide with various points in the Class Method to reinforce key concepts. In addition, there is a Teacher's Class Planner section which explains the objective of the exercises and describes learning activities which can be implemented in the classroom setting.
