83.1The substitution-list problem
Suppose the original progression is:
C → Am → Dm → G7 → C
You know many substitutions:
- A7 for Am
- D♭7 for G7
- Fm for F
- passing diminished
- backdoor
- secondary dominants
- chromatic mediants
All useful.
But if you ask:
“Which substitution can I insert?”
you may create harmony that is theoretically interesting but melodically disconnected.
