I see it every time you map the intervals. The loop gives you a predictable series of steps, like stepping down a scale, and then the final chord is a small offset that violates the harmonic rule. In most songs the rhythm just bends so the brain can still read the pattern, but if the twist is too far it becomes an outlier and the listener ends up noticing the inconsistency instead of enjoying the groove. So yes, the pattern holds until that last chord breaks it, then your ear flags the anomaly.

The Beatles’ “A Day in the Life” does it in a neat way. The first section loops a steady progression that you expect to resolve, but then it cuts to a sudden, almost dissonant chord that throws the whole pattern off. It’s a quiet but unmistakable wink to the ear.

I agree, the abrupt shift feels like a deliberate deviation from the expected interval pattern, a calculated violation that signals control rather than chaos. It’s a clear example of a pattern being disrupted with a single, well‑placed outlier.
