In the earlier blog: Music Chord Theory Part I though IV
I discussed some of the most important chords and there number formulas. By memorizing
the most common chords you can create your own unique chord voicings and any chord.
Every note position in a major scale is assigned a coinciding number position.


Example given in key of C major. Number positions are the same for all fifteen keys.


C major note names = C, D, E, F, G, A, B, C, D, E, F, G, A, B, C

C major scale numbers = 1/R, 2, 3, 4, 5, 6, 7, 8/R, 9, 10,11, 12, 13, 14, 15/R



Buy taking a basic form or shape then adding, sharping or flattening specific tones you can create any chord.


Major = R, 3rd 5th (in the key of C or C as the starting or root note the notes are C, E, G).
Minor = R, b3rd, 5th (by flatting or lowering the 3rd scale degree of the C major scale to Eb you create C minor = C, Eb, G. b means flat or one half step lower in tone on guitar one fret distance towards head).
Augmented = R, 3rd, #5 (in the key of C the notes are C, E, G#. # means sharp or one half step higher in tone towards body.
Diminished = R, b3rd, b5th (in the key of C the notes are C, Eb, Gb).


Diminished chords:
Minor major 7th/b5 = R, b3rd, b5th, 7th in C = C, Eb, Gb, B.
Minor 7th/b5 = R, b3rd, b5th, b7th in C = C, Eb, Gb, Bb.
Diminished 7th = R, b3rd, b5th, bb7th in C = C, Eb, Gb, A.
Diminished /b6 = R, b3rd, b5th, b6th in C = C, Eb, Gb, Ab. (synonym Ab7 1st inversion)
Diminished /bb6 = R, b3rd, b5th, bb6th in C = C, Eb, Gb, G.
Diminished /b9 = R, b3rd, b5th, b9th in C = C, Eb, Gb, Db.
Diminished /9 = R, b3rd, b5th, 9th in C = C, Eb, Gb, D.
Diminished /#9 = R, b3rd, b5th, #9th in C = C, Eb, Gb, D#. (synonym Ab7 1st inversion)
Diminished /##9 = R, b3rd, b5th, ##9th in C = C, Eb, Gb, E. (synonym Ab7+ 1st inversion)
Diminished /11 = R, b3rd, b5th, 11th in C = C, Eb, Gb, F
Diminished /9/11 = R, b3rd, b5th, 9th, 11th in C = C, Eb, Gb, D, F.
Diminished /9/#11 = R, b3rd, b5th, 9th, #11th in C = C, Eb, Gb, D, F#.
Diminished /#9/#11 = R, b3rd, b5th, #9th, #11th in C = C, Eb, Gb, D#, F#.
Diminished 7th/9 = R, b3rd, b5th, bb7th, 9th in C = C, Eb, Gb, A, D.
Diminished 7th/11 = R, b3rd, b5th, bb7th, 11th in C = C, Eb, Gb, A, F.
Diminished 7th/9/11 = R, b3rd, b5th, bb7th, 9th, 11th in C = C, Eb, Gb, A, D, F.







Now transpose these to each position (register) of your instrument, then to all 15 keys.

For guitar learn above chord forms on all four string groups: EAD, ADG, DGB, GBE.
