The Mathematician and the Beatles chord

Jason Brown of Dalhousie University published a study called “Mathematics, Physics and A Hard Day’s Night.” The abstract reads, in whole: “In this article we shall use mathematics and the physics of sound to unravel one of the mysteries of rock ’n’ roll – how did the Beatles play the opening chord of A Hard Day’s Night? The song may never sound the same to you again.”

(Thanks to investigator David Holzman for bringing this to our attention.)
