As someone who's recently tried to get into (basic) music theory, trying out the chord progressions you mentioned was fun! Do you happen to know of any resources that go through more of these well-known chord progressions?

I'm also wondering if these chord progressions work the same way for all scales, or if, for example, the 'sad but I have closure'-type ending only sounds that way in major scales? From experimenting I think it only works for major scales, but I'm not sure :)
