This is possibly the coolest dream I've ever had!

IRL, the latest topic in my Harmony book is the Pivot Chord. I was having a lot of trouble understanding this topic and felt that I was at an impasse. Well, last night I had a dream where I was talking to my childhood piano teacher, and I asked her about the Pivot Chord, and she gave me some hints as to how to identify them! In the dream she gave me hard and fast rules, and when I look at my Harmony book I can see what she told me isn't hard and fast rules, but it was still helpful!
