Chuck Berry's "Johnny B. Goode" opens with one of the most immediately satisfying chord progressions in rock and roll: a driving Bb–Eb–F–Bb that sets the key, stakes out the tonic, lifts through the subdominant and dominant, and snaps back home with a sense of momentum that feels both inevitable and thrilling. The movement from Bb to Eb carries a broad, open quality, while the push through F creates just enough tension to make the return to Bb feel earned rather than casual. Released in 1958, the song helped define the vocabulary of rock and roll guitar playing for generations to come. That opening sequence rewards players as much as listeners — direct, logical, and immediately recognisable.
