Figuring out Another Brick In The Wall Pt2 on my own - thanks to theory course

I’m on module 4.2 in Justin’s music theory course and I’m seeing some of it pay off. I am figuring out Pink Floyd’s ‘Another Brick in the Wall’ Pt.2 with only my guitar. Even figured out most of the solo so far. I listened to the song once recently, and it’s now pouring out of my head onto the guitar.

The only thing I looked up was the song key. Amazing how knowing the key actually helps now.
Besides understanding keys, the section on triads helped me immensly here.

This is really the first time I have tried to play someone elses music since I started the course. Playing guitar is becoming much more fun.
