Now allow me to explain why IMHO that is an utterly useless list.
To help beginning players - we are in the General Instruction area here-, the nomenclature of chords should be made as simple as possible. 'Simple' means both systematic and generally accepted.
Chords are most easily known from their intervals. A 7th chord consist of 4 notes, a root, a third, a fifth and a seventh. The root won't vary, the third may be major or minor, the fifth may be perfect, diminished or augmented and the 7th may be minor, major or diminished. There are eight different seventh chords (10 in theory, but never mind):
1. diminished seventh (1, b3, b5, bb7)
2. half diminished seventh (1, b3, b5, 7)
3. minor seventh (1, b3, 5, b7)
4. minor major seventh (1, b3, 5, 7)
5. dominant seventh (1, 3, 5, b7)
6. major seventh (1, 3, 5, 7)
7. augmented seventh (1, 3, #5, b7)
8. augmented major seventh (1, 3, #5, 7)
They are ranked like this because
- 1-4 have b3, 4-8 have 3;
- 1-2 have b5, 3-6 have 5, 7-8 have #5;
- 1 has bb7, other uneven numbers have b7, even numbers have 7.
Anyone who is able to post on TB should also be able to remember them this way, even if he is a Phrygid from Doromyxolydionia.
A half-diminished 7th is not (1, b3, b5, 7) it is (1, b3, b5, b7) Therefore, the uneven numbers do not all have "7" and your systems makes even less sense. Sorry, but this isn't horse-shoes.
