What is the word for the entire chord progression of a song? Small sequences of harmonies are call progressions, can we also call the entire sequence of chords in a song a progression, or is there a better word?
There is no technical term for it that I know of. The only word I can think of is "changes", often used by jazz players.
Do you know the changes for "I got rhythm"? If you do, then you can comp on it or improvise on it because you know every chord, all the way through. That is, you know the entire chord progression of the song.
There's no other word for it, so that must be the word.
