I have a high school guitar program and my “go to” method guitar book is the First Year Guitar Hands On Training (H.O.T.) book as it contains many units of study (14 basic chords w/ progressions, E & A barre chords w/ progressions, scales, note reading in 1st and 5th position, blues, power chords, arpeggios using PIMA and more. Included are written tests, worksheets and proficiency rubrics. I supplement this with the WebRhythms exercises from Vic Firth, simple ensembles from the Doberman Editions and beginning solos from the Bridges Series. All of these combined cover a lot and lays a solid foundation for my students.
