J. Anthony Allen explains the cadential six-four chord and how it expands the tonic by using passing tones and arpeggiation. The bass line moves by chord tones, and the six-four often undoes previously learned harmonic rules, making it essential for advanced theory work.
Sam. By treating the notes of the tonic chord as passing tones, which is kind of a head scratcher. I totally get it. It's weird. But what we've done here is. And then we have a I chord again. Okay? So obviously what I'm concerned with is this different chord because this is all I. So what's happening here? F, B flat D. So if we put all those notes in order, we would spot in context one of those arpeggiating 64 chords. Now remember what you're looking for here for the bass line to start moving up by chord tones, right? To just walk up its own chord. So let's hear it. And then this is one that results from doing something else. It's kind of the byproduct of another kind of motion. So let's take a little bit of a step back to walk through this. Let's switch. Hey everyone. Welcome to Music Theory Part 8. If you've been following along in this sequence of classes, you know, basically what we're up to here, we're going through my whole college level curriculum and we're nearing the end of what would be the second semester, the topics covered in the second semester with this class. So if you stick with all of these classes, you will go through my entire four semester college curriculum as long as I keep making, and I plan on, keep on making them. So in this part, in part eight, we're going to be focusing on expansion of tonic, in particular this goofy 64 chord. We're going to be working a lot with the cadential six four. It's called. Now why does this weird little chord get its entire own class? And it's because this chord has the unique properties of undoing some things that we've already learned. I know that's frustrating, but it'll all make sense, what you get once you get inside this course. I'm not going to lie, this is the hardest one so far. We're going to get into some exceptions, some, some new rules, some different ways that things that you already know can work. So it's really important course. If you're trying to really understand music theory, it's vital that you get through this course and you understand these new topics that we're talking about. Because as we move forward into more music theory, you're gonna need to understand how some of this stuff works. So I hope you decide to join us in this class. There's a bunch of worksheets, a bunch of examples, a bunch of things for you to play around with in the class. So Please join me on the inside and let's get started right away. It.
