Demystifying Chord Symbols

Here I, hopefully not too feebly, explain how the chords got their names.

To create dominant chords I used a two octave C Mixolydian scale...

CDEFGABbCDEFGABbC

C - CEG
C7 - CEGBb
C9 - CEGBbD
C11 - CEGBbDF
C13 - CEGBbDFA

To create Major versions I used a two octave C Major scale...

CDEFGABCDEFGABC

C - CEG
Cmaj7 - CEGB
Cmaj9 - CEGBD
Cmaj11 - CEGBDF
Cmaj13 - CEGBDFA

To create Minor versions I used a two octave C Dorian scale...

CDEbFGABbCDEbFGABbC

Cm - CEbG
Cm7 - CEbGBb
Cm9 - CEbGBbD
Cm11 - CEbGBbDF
Cm13 - CEbGBbDFA

The Modes - C Dorian

The formula for creating the simple practice progression in the video -

C Dorian - relative major is Bb major

The IV and V chord of the relative major is Eb and F.  Place those two chords over the mode's root, C, and you get...

Eb/C / / / | F/C / / / |
