So the GDEC-chord combination got me searching through the Internet, trying to find some theories about that. I stumbled across this Stand-up comedian who talks about Pachelbel’s Canon in D and all the songs that uses the same chords!

Using that chord combination is of course an instant win, as everybody likes that combination, but the guy kinda smuggles (like U2’s “With or Without You” is clearly GDEC – I think) and uses some songs that use the GDAC-chord combination, instead of the DABF#GDGA (which incidentally has the first 3 chords if you shift it to GDEBCGCD).

The Digg-entry had a link to this: The History of Pop Music in Four Notes, which is a guy who does the same, but with the GDEC-chord combination. The Digg-entry has got some interesting comments, where I will quote one (Imushi):

“It’s cute but it’s not accurate. It WORKS but it’s not “right” – the melodic lines Fit over the chords but do not necessarily have the same Harmonic Progression in actual context. An example is Adam’s song which has a verse progression of I – IV – vi – IV, which is in fact close to the I – V – vi – IV he’s using, close enough to make it sound like it works, and it works. But it’s fudging the truth.

Yeah though, I – V – vi – IV is wildly popular. It won prom king AND queen.”

This is what sort of explains my take on some of the Pachelbel crossover song smuggling in Rob Paravonian’s video!
