Computer model charts musical evolution of the Beatles

Computer scientists have developed an algorithm that correctly accounts for the Beatles' growing musical sophistication, and is able to correctly determine in what order the band recorded its works.
It demonstrates scientifically how the structure of the Beatles music changes progressively from one album to the next.

...It starts with the Beatles' first album, "Please, Please Me", and followed by the subsequent early albums, "With the Beatles", "Beatles for Sale" and "A Hard Day's Night".

"Let It Be" was the last album released by the Beatles, but the algorithm correctly identified those songs as having been recorded earlier than the songs on "Abbey Road".

"People who are not Beatles fans normally can't tell that 'Help' was recorded before 'Rubber Soul', but the algorithm can," Shamir said.
