MATHEMATICIAN ANALYZES MYSTERIOUS OPENING CHORD IN "A HARD DAY'S NIGHT"
Jason Brown (Dalhousie University) is in the news for his work analyzing 
the opening chord of the Beatles' song "A Hard Day's Night." It was 
known that most of the chord was played by George Harrison, but the 
exact nature of the chord remained a mystery for 40 years. Brown used a 
Fourier transform to analyze the frequencies and solve the mystery. He 
found an F note in the opening sound that could not be played on 
Harrison's 12-string guitar and deduced that the note was part of a 
piano chord played along with the guitar. The Halifax Chronicle Herald 
has more about Brown and his research, at
