Analysis
What each numeral is doing.
Roman numerals name a chord by its position in the key rather than by its letter, which is why one progression works in every key. Uppercase is major, lowercase is minor, ° is diminished, ø is half-diminished, and a leading ♭ lowers the root a semitone.
- I
Tonic
Home. Everything is measured against it and everything wants to return to it.
- vi
Submediant
The relative minor. Same notes as the tonic, opposite mood.
- ii
Supertonic
The classic set-up chord — it leans on the dominant and rarely stands alone.
- V
Dominant
Maximum tension. The leading tone inside it pulls hard back to the tonic.

Why it works
The reason it sticks.
The Gershwin AABA form; basis of bebop heads. The memorable part is the motion: each chord pulls toward the next in a way that feels both surprising and inevitable, and the cycle closes cleanly enough that you can loop it for three minutes without anyone getting bored.
Once the Rhythm Changes pattern is in your ear you will start hearing it everywhere. That is not a coincidence — writers reach for it because the tension-and-release shape is doing the emotional work before the melody even arrives. Change the key and nothing about that changes; only the letters do.
