Learning to apply the guitar number system to chord progressions will literally kick down the door to mastering the guitar fretboard.

In this lesson we take a look at the chord progression and scales used to play the intro solo to Soulshine by The Allman Brothers Band.

Chords within a given key have a function, or role they play within the key. Understanding these chord functions can help you understand why some chord progressions sound good while others sound not so good.

Playing chord progressions by position is a great way to familiarize yourself with the different chord voicings found all over the neck. It helps open up the fretboard and reduces dependency on only playing open chords and basic barre chord shapes.

Building chords from the major scale sets the foundation for writing and understanding chord progressions, transposing to other keys, and developing your ear as a guitarist. In this lesson you’ll learn how chords are constructed from the major scale by stacking 3rds, what determines the quality of these chords, and how these chords map to the fretboard.
