Three progressions — I–V–vi–IV, I–vi–IV–V, and a ii–V–I with sevenths — each just a line of integers choosing the chord per bar. A line of numbers, read as harmony.

A line of numbers, as harmony

A chord progression here is nothing special — just a line of integers, one chord-degree per bar:

# the I–V–vi–IV "pop" progression
chord_line: 1 5 6 4

It’s the exact same kind of line that, elsewhere, is a melody. Read as a chord_line, each number picks the chord; a voicing stacks the triad (or seventh) on top:

source:
  kind: notes
  chord_line: prog-pop     # 1 5 6 4
  voicing_line: triad      # 1 3 5
  scale: major

Harmony, melody, rhythm — the same substrate (a line of integers), a different projection.
