I really sank some time into this one compared to the other two or three books I've been reading on and off. Certainly am learning a lot. I remember getting up to musical scales last time with a different music theory book, and kind of hitting a wall of understanding. This book has helped get past that, gradually discerning what is at first ambiguity in the music vocabulary.
I found myself watching some music analysis videos on Youtube and understanding what was going on a lot more, although with a bit of mental lag. I'm almost done with this book and just need another stretch.
