Homework — Workshop 5

A. Basic form

Play 12-bar C blues without looking.

Say bar numbers aloud.


B. Quick change

Play the quick-change version with F7 in bar 2.

Switch between basic and quick-change forms without stopping.


C. Shells

Play all 12 bars using:

LH roots

RH 3rd/7th only.

Make every change smooth.


D. Blue-third drill

Practice:

E♭→E

E♭→E

over C7.

A♭→A

A♭→A

over F7.

B♭→B

B♭→B

over G7.

Then use each in a short phrase.


E. Form targets

Improvise one chorus where:

bar 5 must land on A.

bar 9 must land on B.

bar 11 must clearly return toward C7.


F. AAB solo

Create:

bars 1–4 = statement.

5–8 = related variation.

9–12 = answer.

Use only one 3-note motif.


G. Jazz-blues changes

Practice:

| C7 | F7 | C7 | Gm7 C7 | | F7 | F♯°7 | C7/G | A7 | | Dm7 | G7 | C7 A7 | Dm7 G7 |

First roots.

Then shells.

Then full chords.


H. Tritone substitutions

Practice:

Gm7 → G♭7 → F7

Gm7 → G♭7 → F7

and:

Dm7 → D♭7 → C7.

Listen to the chromatic bass.


I. Walking bass

Create a basic quarter-note walking line for all 12 bars.

Prioritize:

  • root on new chord
  • chord tones
  • chromatic approach into bars 5 and 9

Do not worry about sophistication.


J. Four-chorus solo

Record:

Chorus 1

minor pentatonic, sparse.

Chorus 2

major/minor mixture.

Chorus 3

chord-tone targeting.

Chorus 4

motif development over jazz-blues changes.

Listen for whether intensity grows naturally.
