Discovery I should have already known about (DISHAKA) #1

Hooray, first video!  I was sitting on my couch a few minutes ago wondering about crescendos and why they work so well in songs they work so well in.  And I thought about that progression you often hear when you go to a concert and the music is building -  it's called an "extended dominant" progression, where the V of the chord played directly before is played over and over (i.e. C to F to Bb to Eb...).

And I was also wondering about another progression which you've probably heard as well where an extended dominant progression starts but stops after the second chord to move up from the first chord by a step.  This progression is in pop music a lot.  One that comes to mind is "Love you like a love song" by Selena Gomez.  And I realized it works because the bass line is moving up the diatonic scale - it's just taking two chords to do it.  If that was true I was going to feel a little silly for not realizing that until now.  It's slow, but exciting.  You get the illusion of volume even by not playing louder.

So I decided to try my theory.  Note that every two chords the bass line moves up the diatonic C scale.  I got distracted and started playing with chords substitutions toward the end, but overall I think it sounds kind of cool.  And yeah I feel silly now.
