101.3A simple example

Instead of writing:

Bar 1: Cmaj9 voicing X.

Bar 2: Am7 voicing Y.

Bar 3: Dm9 voicing Z.

Write rules:

  • first phrase stays sparse
  • melody always foreground
  • bass moves mostly stepwise
  • no altered harmony before phrase 3
  • fills only during rests
  • phrase 4 cadence is strongest

Now many note-level realizations can work.
