Hacking the CAGED System: Diatonic Harmony
Most guitarists have gaps. They can play scales and chords but can’t connect them. They come up with a chord progression and don’t know where to go next. They can solo over one chord but lose the thread when the changes happen underneath them. The missing piece is almost always the same thing: diatonic harmony.
Diatonic harmony — understanding how everything in a key relates to everything else — is the single concept that ties scales, chords, arpeggios, modes and improvisation together into one coherent system. Once you have it, the fretboard stops being a collection of unrelated shapes and starts making sense as a whole.
Hacking the CAGED System: Diatonic Harmony maps that system directly onto the guitar fretboard in a way that’s immediately practical and usable.
What the book gives you
- A complete system for constructing all the components of any key signature on the fretboard — chords, scales, modes, arpeggios and triads, all from one framework
- The ability to improvise freely within any key using modes, pentatonic scales, chord tones and arpeggios — not as separate ideas but as parts of the same connected system
- A practical method for building diatonic chord progressions using chord synonyms and alternatives — so you always know which chords work together and why
- The tools to create modal chord progressions that can be as simple or as complex as you want
- A framework for soloing over chord progressions with genuine direction — knowing what works over each chord and why
Who it’s for
Guitarists who know chords and scales separately but can’t connect them. Players who want to understand why certain chords work together rather than just memorising progressions. Anyone who’s felt lost when a chord progression moves somewhere unexpected. This book puts all those options within reach and leaves you free to do some of your best playing and writing.
Note: it is not a prerequisite to have worked through Hacking the CAGED System — Book 1, though the two books complement each other well.
