I listened to the audio version of this, narrated by Bryan Howard. I'm sure I'd have rated it higher had I not listened to it while driving. One needs a keyboard to assist in understanding intervals and what not. I'm guessing if one has spent more time than I staring at a keyboard, that mightn't be necessary. Also, the title is wrong here--It's Music Theory: From ABSOLUTE Beginner to Expert-etc., so I thought, "This is for me!" Well, I think the idea is that you might be a fabulous musician and still be an absolute beginner to formal music theory. Still, I did learn stuff. :-) ( )
