## Definition

A **_chord progression_** is a sequence of chords played one after another in a piece of music, forming its underlying harmonic structure.

In this channel's material, **_chord progression_** comes up in the context of exploring piano playing and music theory with an AI coding agent. The video explores how Codex can teach piano and music theory in real time, which means understanding not just single chords but the *sequences* of chords that give a piece of music its movement and character [^2f7cb0cf@0]. A **chord progression** is the connective tissue between harmony and melody: once you can name individual chords, exploring progressions is how you start to understand why a piece of music feels the way it does — and how an AI assistant can walk you through that structure in real time as you sit at the keyboard.- A **_chord progression_** is a sequence of chords played in order, forming the harmonic backbone of a piece.- In this material, progressions are explored in the context of using **Codex** to teach piano and music theory interactively.- Understanding progressions is a step beyond naming individual chords: it is how you make sense of a song's overall harmonic movement.
