List of all Parent/child Combinations
| Triads (3-note chords) | 4-note chords (including sevenths) | 5-note chords (including ninths) | 6-note chords (including elevenths) | 7-note chords (including thirteenths) |
| 8-note chords | 9-note chords | 10-note chords | 11-note chords | 12-note chord |
| From the church modes | From harmonic minor | From whole tone patterns | From octatonic patterns |
Pedigree is how a chord is formed. All chords start with a unison note, P1.
Notes of the interval M3 are P1 and M3, or R,3, so M3 is said to be a "parent" of P1.
The major chord, R,3,5 contains M3, so the major chord is a parent of M3.
The 7 chord contains the major chord, so 7 is a parent of major.
Chords have more than one parent.
Maj7 also contains all the notes of the major chord, so Maj7 is also a parent of major.
A chart with all the parent forms would have millions of lines, so in
the detailed charts the most likely parent/child combination is
chosen. Other
pedigree patterns are possible.
The charts have been designed so that the more common intervals and chords have priority.
