Real Numb3ers solve real mystery
Listen to the opening chord of the Beatles’ A Hard Day’s Night and try to figure out its tablature. Go ahead, join the countless musicians who have been trying to emulate that sound since 1964. Four years ago Dr. Jason Brown of Dalhousie University’s Department of Mathematics and Statistics – and an amateur musician himself – decided to have a go.
He used Fourier transforms to reverse engineer the chord. (True confession – I took calculus and acoustics but never got as far as Fourier transforms.) His conclusion is that the sound is impossible to play without the addition of someone – probably Sir George Martin – adding a little piano. It’s not really news, but nonetheless yay math. (Via /.)
