The rules

The construction rules F7♭13 follows

  1. 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.

  2. A third on top makes a 7th chord

    A major 7th over a major triad is maj7, a ♭7 is a dominant 7. Over minor you get m7 or m(maj7); over diminished, m7♭5 or the °7, whose 7th is lowered twice.

  3. Keep stacking for extensions

    The 9th, 11th and 13th are the 2nd, 4th and 6th an octave up. Each one sits on the stack below it: a 9th chord holds a 7th, a 13th holds the 9th and 11th in theory.

  4. 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.

  5. Drop what adds least

    A guitar chord has four to six notes. When the formula holds more, the 5th and then the 9th go first: the root, 3rd, 7th and top extension still say exactly what the chord is.

  6. 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.

  7. Alter a dominant for tension

    Raise or lower the 5th or the 9th, or add a ♯11 or ♭13, and a dominant 7th pulls harder towards the next chord: G7♯9, G7♭9, G7♭13.
