7.19First harmonization strategy
When given a melody in a major key, try this sequence:
Step 1
Use only:
I
for as long as it still sounds plausible.
Step 2
When I stops fitting or becomes boring, try:
IV
Step 3
Before important return to I, try:
V7
Step 4
Add:
vi
for softer tonic-like color.
Step 5
Add:
ii
before V.
This prevents you from overcomplicating things.
