a fact i've always got a little giggle from is that a good portion of the soundtrack for the original DOOM is in 12 bar blues

It’s funny how certain chord progressions are instantly evocative of a certain era of music. The ‘Closing Time’ progression instantly makes me think of turn of the millennium / noughties music as soon as I hear it, even when used by someone like Phoebe Bridgers in completely contemporary songs.

I legitimately burst out in laughter with the Paramore -> Olivia Rodrigo cut. HAhahahaha very well played David.

As a band geek back in my school days, I always wondered why every American high school and university fight song sounded almost the exact same. With videos like this, I've actually been able to put it into words. They all have almost the exact same 16-bar "Fight Song" Chord Progression. It was always some variation on: ||: I | I | I | I | V | I | V | V | I | I | IV | iii | IV | I | I V | I :||

I never realized that U2's I Still Haven't Found What I'm Looking For uses the 12 bar blues progression. With major 7th's instead of dominant, it certainly doesn't have much of a blues flavor, but does fit the progression.

Shoutout to "Boulevard of Broken Dreams" for using two of these progressions. Also, another common variation on the 12-bar blues that wasn't covered here: bar 2 sometimes uses the IV chord. You will probably hear the term "quick-change" used for this variation.

You’ve done secondary dominants, but I think it would be a really interesting video if you covered secondary leading tones. Those can get really fun, and I’d very much like to learn more about them. I know what they are but never how to use them!

I love the 3 TSwift songs in a row, and then including "Half of my heart" which has Taylor on backup Vox

Love how you include a wide spectrum of music genres to these videos Also this helps explain why I kept getting reminded of "Misery Business" in "Good 4 U" they share the same chord in the same instrument (Guitar), have a female vocals and deal with similar topics (Something in a School Drama)

10:46 What's My Age Again? actually switches to the I, V, VI, IV in the chorus, so it's actually the same progression as in the verse but shifted along by one chord. The intro riff is actually brought back in in the outro, only shifted along by one note. Always thought it was clever how they did that :)

Merci beaucoup David. I've been watching you for years, and I'm not a musician. Ahem, I wasn't a musician. I bought a piano last month and started at 65. Now your videos make much more sense since I'm also taking a foreign language course.

"Plagal cascade" is a fancy name for something you learn in classical harmony as "Ascending 5th sequence. These progressions are less goal-directed than descending 5ths but very common in all music. In minor keys the ascending 5th sequence would benefit by starting on bIII since the diminished chord on scale degree ^2 would make an ascent from the i chord undesireable. It is for this reason you will usually see the "plagal" motion starting on the bIII chord. It allows us to bypass the dimished triad and use the ascending 5th sequence.

In the jazz idiom, it's the chord progression of "I Got Rhythm" by the Gershwins that became one of the most common. Several be-bop era tunes are written over "Rhythm Changes", and commonly played by jazz musicians at jam sessions as a medium for improvisation.

Important note: the Plagal Cascade (i-bIII-bVII-IV) is dorian. So you can write the melody in dorian or minor pentatonic quite easily. (You can even sneak an aeolian b6 in there, provided you keep it away from the IV chord.)

It's interesting to have the Axis Progression (and the 'other' Axis Progression) and the Closing Time progression in here mentioned all together because in Benny's (the pianist from Axis of Awesome) Six Chord Song video he blends all together with a few more and it's been my warm up song for years as adding the two extra chords makes it go from hundreds of pop songs to almost all of them.

That transition from Attention to Sweet Dreams was so smooth

I remember reading how they write pop music to play with your emotions and they have it down to a science. My guess is that with the Axis of Awesome chord progression they switch the order of the IV and V just so that when you stop listening to the song you just run it over endlessly in your head. If it ended on the 5 then the song would be over and I wouldn’t go out and buy big macs or whatever it is pop music these days is on about. Having a looping chord progression in your head is maddening!

When you played the Can't Stop progression I immediately heard Can't Hold Us, and Heartbeat by Childish Gambino. Both songs that use this chord progression on piano very prominently.

Your song examples in this one are fantastic! I discovered that my heart is owned by the "Plagal Cascade". Every one of those song examples is an all time favorite of mine! Of course the 12-bar Blues kicks some serious ass, too, but nothing like that first one. Great video!
