If this has been asked recently, or if the questions is in the archives, please excuse me. My question: What is a stacked triad? I assume it's what it sounds like, say in the key of Gmaj, a common I, IV, V7 progression, you would play, in succession, G B D, C E G, D F A? I've been reading more theory and the book I downloaded didn't have a great description, or at least I didn't understand it. So, any help wo uld be greatly appreciated. Thanks.
