How it works on guitar
Use the concept as a practical way to choose, move, or revise chords.
Diatonic chords are the chords built from the notes of a key. They give you the default chord family before you borrow colors from another key or add secondary dominants.
On guitar, start with the most playable members of the family. In G major, G, C, D, and Em are open and practical; Bm is diatonic too, but it may need a barre or simplified voicing.
| Concept | Guitar meaning | Example |
|---|---|---|
| Major key | I ii iii IV V vi vii° | C Dm Em F G Am Bdim |
| Natural minor key | i ii° III iv v VI VII | Am Bdim C Dm Em F G |
| Common guitar use | I, IV, V, vi | Most pop, folk, rock, and country loops start here |

- Name the functionSay the roman numeral or borrowed-chord role before playing the change.
- Move the voicingTry a smaller triad or seventh-chord grip so the theory is audible, not muddy.
- Write one variationChange one chord in a familiar progression and decide whether the sound improves.
