3.97The larger lesson

A progression like I–vi–ii–V seems simple because there are only four chords.

But it contains:

  • tonic prolongation
  • circle motion
  • guide-tone voice leading
  • secondary-dominant opportunities
  • substitutions
  • modal/style possibilities
  • endless melodic variation

Simple harmony can be a deep laboratory.
