The construction rules A6 follows
Start from a triad
Root, 3rd and 5th, stacked in thirds. The 3rd makes it major or minor; the 5th makes it diminished or augmented when it moves.
No 7th, no stack
6, add9, add11 and 6/9 are a triad with a colour note, not a stack. Without a 7th the chord sounds open rather than jazzy.
On guitar, something has to give
Each extension takes the string of a triad note that matters less, usually the 5th, or gets a string of its own. The root and 3rd stay: they say what the chord is.
The root can move down
When an extension needs the root’s string, the root can drop to the string below the triad: an anchored voicing keeps the bass and frees a string on top.
All the rules, with examples, in the guide to the chord library.
