Homework for Module 12

A. Secondary dominants in C

Memorize and play:

A7 → Dm

B7 → Em

C7 → F

D7 → G

E7 → Am

and:

G7 → C

For each one, identify the chromatic note that creates the leading-tone pull.


B. Enriched progression

Practice:

Cmaj7 → E7 → Am7 → A7 → Dm7 → G7 → Cmaj7

Cmaj7 → E7 → Am7 → A7 → Dm7 → G7 → Cmaj7

First block chords.

Then smooth inversions.

Then shells.


C. Chromatic inner lines

Hear and play:

G → G♯ → A

G → G♯ → A

over:

C → E7 → Am

C → E7 → Am

Then:

C → C♯ → D

C → C♯ → D

over:

Am → A7 → Dm

Am → A7 → Dm

Then:

F → F♯ → G

F → F♯ → G

over:

Dm → D7 → G

Dm → D7 → G


D. V7/V

Practice:

D7 → G7 → C

D7 → G7 → C

then transpose:

A7 → D7 → G

A7 → D7 → G

and:

G7 → C7 → F

G7 → C7 → F


E. Three levels of approach

Choose destination F.

Play:

C → F

C → F

then:

C7 → F

then:

Gm7 → C7 → F

Gm7 → C7 → F

Repeat with destination G.


F. Melody check

Take a simple melody you already harmonized.

Insert one secondary dominant.

Then ask:

  • Does the melody note fit?
  • Does the chromatic alteration clash?
  • Can a different voicing solve it?
  • Is the extra tension actually desirable?

G. Improvisation

Loop:

Cmaj7 | E7 | Am7 | A7 | Dm7 | G7 | Cmaj7

Use mostly chord tones.

Make sure you deliberately play:

G♯ over E7

and:

C♯ over A7

at least occasionally.

Hear those notes resolving upward.
