They missed Let it Bleed from Stones...

Let it Bleed - Rolling Stones

Haha, yes that's true Only 4 chords are enough. Thanks for sharing Adelaide!

Thanks for the link Adelaide.

BTW, the chord pattern in this video is C G Am F (not Em)

And yes, some chord patterns are "standards" which sound good to our ears (at least ears used to listen to western music).

I used to play lots of jazz music, and two chord progressions are very well known by jazz musicians. That's what we call 2-5-1 and 6-2-5-1. I guess such patterns also exist for pop music or other genres.

For more info, you can google "2 5 1 chord progression" or "6 2 5 1 chord progression".

I forgot to tell that I thought of "Goodbye Yellow Brick Road" when the guy played the chords.
