Picking up where Tekker left off (good info by the way).

The C major scale harmonized looks like this.

1 2 3 4 5 6 7 8
C D E F G A B C
E F G A B C D E
G A B C D E F G
B C D E F G A B

The chord qualities are

1 and 4 are major 7ths

2, 3 and 6 are minor 7ths

5 is a dominant 7th

and 7 is a min7b5 chord

3 and 6 will substitue for 1 because they each share 3 notes, hence the term common tone substitution.

2 and 4 sub for each other and 5 and 7 sub for each other.



Now let's take the last 2 bars of a song in C which is a great place for a turnaround.
A turnaround is a chord progression that leads back to the beginning of a song, typically it is a 1 6 2 5 progression. In C that would be

Cmaj7 Amin7 Dmin7 G7

We could add notes for additional color


Cmaj9 Amin9 Dmin11 G13



We could add a common tone sub like 3 for 1. That gives us

Emin7 Amin7 Dmin7 G7 and you could still add extensions to this if you want.

Because the 5 to 1 resolution is so strong you can change some of the chords to dominant 7ths like this.

Emin7 A7 D7 G7 and if you add tritone subs you can get other possibilities like these.


Emin Eb7 D7 Db7. Tritone subs are a great way to get to a chromatic bass line. Notice the movement E Eb D Db.


Any combination will work between the regular chords and the tritone subs. Here are a couple of more.
Cmaj7 A7 Ab7 G7


Cmaj7 Eb7 Ab7 G7


Emin7 Eb7 Ab7 Db7


It would be easy to keep going here but I am going to stop here and see if anymore questions come up.


Best Wishes,

Bob
