Chord theory is chord theory, Bob, whether someone's singing along with it or not--not being a "song" doesn't change it. Knowing that I and V go along nicely with IV--whether it's in chording, arpeggiating, fancy pattern pickin', the foundations of melodic structure, or just a-strummin' along with a simple tune--isn't a profound revelation to anyone who's ever seen the Circle of Fifths, as I did in my Music Theory text a good *mumbley-mumbley* years ago. It's so simple, in fact, that it's been the foundation of many a rock 'n' roll career.
You still haven't said a single conversational thing to anyone in this thread, so I stand by the last bit of my post, and considering you've never heard me play or actually conversed with me about music theory, you haven't the least bloody idea how "developed" I am, whatever the hell that's supposed to mean. In the vast rainbow of opinions at the Mudcat, I have actually seen you make worthwhile contributions elsewhere. This ain't one of them--it's nothing but antagonistic trolling.
No more posting in this one for me; I'll just read with amusement.
