The same four numbers — 1 5 6 4 — read two ways. First as a melody, four notes in turn; then as harmony, the very same line choosing four chords. One line of numbers; the meaning comes entirely from what reads it.

One line. A melody, or a harmony.

Four numbers:

line: 1 5 6 4

Read as a melody, each number is a scale degree — one note at a time:

read-as: melody     # 1 5 6 4  →  C  G  A  F

Read as harmony, the same four numbers each choose a chord, and a voicing stacks a triad on top:

read-as: harmony    # 1 5 6 4  →  C  G  Am  F   (the I–V–vi–IV progression)

Nothing in 1 5 6 4 says “melody” or “harmony” — or even “music.” The numbers are pre-semantic. Meaning arrives only when something reads them through a context: a scale degree, a chord, a section of a song. That projection is the idea the whole engine is built on — the same one that turns a line into a song’s structure.
