Playing the
Changes

From→Through→To is the ii–V–I (said two, five, one)

Playing the Changes is as simple as this: moving from here (point of origin, or the ii) to here (point of destiny, or the I) through here (the bounce, or the V). In music, the destination is the home key. The pivot — the bounce — is where you decide to change direction from where you started. When spoken, it sounds like "two, five, one."

Many of the changes we fear most are not events — they are feelings. And navigating feelings works exactly the same way. The magnitude of emotions shown on the Feelings Wheel mirrors the complexity of John Coltrane's Cycle of Fifths, which shows musicians how all the tones in five octaves are related. When we navigate our feelings toward a desired state, it is rarely a straight path — from sad to happy, for example. Usually you need to bounce. Sometimes more than once.

The ii–V–I is a most important harmonic movement in jazz — not just as metaphor but as precise structural description. It is the reason the music resolves. It is also the reason growth is possible.

Playing the Changes is the jazz practice of improvising through harmonic shifts (chord changes) — finding the note that's true in the new context. You don't play what you planned, you bounce — you pivot. You play what the moment needs, using everything you know. That's not improvisation as chaos. That's improvisation as the highest form of preparation meeting reality.
