This lesson is of the 7 diatonic chords of the C major scale or key. Very important when training the ear to recognize diatonic harmonies and chord progressions. This same progression can be transposed in any key. The degrees of the scale are a great way to communicate with other educated musicians and to understand target notes. Example.. C = 1, D = 2, E = 3, F = 4, G = 5, A = 6, and B = 7. The chord progression of a 1, 4, 5 in the key of C Major would be C Major, F Major, and G Major.. With the chords I gave you those would be Major 7th and Dominant 7th chords.
Memorize this, (Major, Minor, Minor, Major, Major, Minor, Minor flat 5th). That is the qualaties of the chords in order!
The chords in this progression are all A shaped voicings. (Refer to GAGED sequence lesson for details on shaped voicings) The voicing starting with the lowest tone goes as follows...
The formulas for each quality of chord is here,
Major 7th = 1-3-5-7
Dominant 7th = 1-3-5-b7
Minor 7th = 1-b3-5-b7
Minor 7th flat 5th = 1-b3-b5-b7
