Core Thesis

The comparison matters because chord detection measures whether harmonic events can be resolved consistently. Harmonic complexity measures how rich, varied, or surprising the resulting field is once it is resolved.

Where the signals diverge

Chord detection measures whether harmonic events can be resolved consistently. Harmonic complexity measures how rich, varied, or surprising the resulting field is once it is resolved.

What to read first

Read chord detection first when you suspect harmonic blur. Read harmonic complexity first when you want to know whether the song has enough harmonic richness to justify repeated listening.

How to read them together

Together they clarify whether complexity is being earned by coherent harmonic motion or faked through confusion.
