A Hard Day’s Night’s mathematical breakdown

Hope you didn’t have a hard day’s night last night bringing in the new year.

All puns aside, I recently heard this cool story on NPR about how Canadian mathematician Jason Brown of Dalhousie University has decoded the opening chord for the Beatle’s song Hard Day’s Night. He was able to determine that one guitar alone couldn’t have created that sound. So what did? Listen to (or just read) the NPR story to find out!

Brown’s next proposed assignment is actually figuring out who wrote “In my Life,” Lennon or McCartney. We’ll see if mathematical analysis of the music can end a decades old argument.
