Non-chord tones: the notes we threw away
Reducing a score to block chords means every note has to answer one question: are you part of the harmony, or are you just passing through? Doing that reduction across our corpus meant throwing away 3731 non-chord tones — notes that read as part of the melody but don't belong to the chord underneath. Most of those, 1212, are the textbook case: a passing tone, filling the gap between two chord tones a step apart.

The census
Every note our reduction flagged as decoration rather than harmony, by reason:
| reason | count |
|---|---|
| Embellishing tone (neighbor, escape, suspension…) | 2519 |
| Passing tone | 1212 |
2519 of 3731 non-chord tones fall outside the clean passing- tone case — neighbor tones, suspensions, escape tones, and the rest of the embellishment family the "non-chord" bucket lumps together. Knowing a note isn't a chord tone is the first step to reading past it instead of hunting for a chord that explains it.
Hear what got dropped

- When it isn't decoration → Some notes that look non-chord are actually an added tension the chord wants — the color chords surveyed on their own terms.
