It’s been a hard day’s night
And I’ve been working like a dog
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 started playing guitar because I heard a Beatles record—that was it for my piano lessons,” says Jason Brown of Dalhousie’s Department of Mathematics and Statistics with a good laugh. “I had tried to play the first chord of the song many takes over the years. It sounds outlandish that someone could create a mystery around a chord from a time where artists used such simple recording techniques. It’s quite remarkable.”(read more...)
