This has just turned into the weirdest theme week - or the biggest one for music nerds - we've ever done.
Yesterday, we talked about the famous chord progression of Pachelbel's "Canon In D". Turns out, there's a lot of songs that use that progression, across many genres - although some do it with more subtlety than Blues Traveler did.
Take Green Day. People in the YouTube comments like to talk about how it's just three chords. It isn't. It's six. D-A-B-F#-G-D-G-A. The band's second single from Dookie won them a Grammy and established the band as superstars - but a lot of people missed the homage to the classics.
Green Day was inducted into the Rock and Roll Hall of Fame in 2015, and guess which classical piece they decided to play?
