Mathematician Cracks Mystery Beatles Chord
The opening chord to A Hard Day’s Night is also famous because for 40 years, no one quite knew exactly what chord Harrison was playing. Musicians, scholars and amateur guitar players alike had all come up with their own theories, but it took a Dalhousie mathematician to figure out the exact formula.
I’m guessing, then, that Harrison and the Beatles were always tight-lipped on this? Maybe they never knew themselves. Of course, that harkens back to the days before extensive liner notes that give credit to the janitor.
