Chord progressions are sequences of chords that form the backbone of most songs. The I–IV–V–I is the foundation of blues and classic rock. I–V–vi–IV (the "four-chord song") is behind hundreds of pop hits. ii–V–I is the cornerstone of jazz. Knowing these by name lets you transpose them to any key instantly.
