Q: what was the first ever chord progression that was called a chord progression when it progressed those chords?
A: i don't remember, but it led to a lot of other chord sequences and sets of chords also getting called 'progressions', misleading the world at large to think chords are always supposed to 'progress', and overshadowing all of the many ordinary times when chords do not need to 'progress' per se, but exist in all the many other ways
