Inside and Out: A Guide to Fretboard Mastery (JamPlay)

If you’ve hit a plateau in your playing and feel limited by your knowledge of the fretboard, this course is designed to help you break through. In Inside and Out: A Guide to Fretboard Mastery, Musicians Institute instructor Jeffery Marshall delivers a clear, structured path to learning the fretboard in a way that’s musical, practical, and transformative.

Rather than overwhelming you with theory or endless patterns, Jeffery uses the powerful CAGED system as a foundation and builds from the ground up. Through a logical progression of 36 lessons, you’ll learn how to see and connect major and minor triads, arpeggios, pentatonic scales, and full major and minor scales across the entire neck. You’ll understand how to use inversions, seventh chords, and harmonic concepts to turn abstract knowledge into usable fretboard fluency.

This course isn’t just about memorizing shapes—it’s about truly understanding how harmony and melody are mapped onto the guitar. With Jeffery’s guidance, you’ll gain the ability to navigate any key, improvise with intention, and craft musical ideas that flow naturally from one position to another. By the end of the course, you won’t just know the fretboard—you’ll own it.

Whether you’re a serious intermediate player or an advanced guitarist looking to fill in the gaps, Inside and Out offers a comprehensive and intuitive method to help you master the neck and elevate your musicianship.
