A cousin, a very good guitarist, once said, People complain about punk rock, but the Beatles weren't exactly Stravinsky. He was talking about the tunes ("This is the third three-chord song in a row."). But he could have said, Lennon and McCarthy weren't exactly Da Ponte.

The Beatles did experiment a lot though. A lot of their songs have very obscure chords and modifications for their time when it wasn’t easy to find information.
