Bebop Blues Chord Changes to Play a Bass in D Flat

Video Transcript

"RYAN LARSON: So now, we've gone through and played through our chord changes to "Mack the Knife." Now, we're going to go through a bebop blues, which is a 12-bar blues, so you want to go home--at home and write down 12 bars on your sheet script or manuscript paper, or you can just write down 12 bars and notate. So you can just kind of get an idea and write these chords down in it. It doesn't have to have musical staff paper; that's all right. But we start right here on our 1 chord, right? D flat, D flat 7 for a measure, and we've got G flat 7, which is our 4, right? D-E-F-G, then back to our 1 chord for a measure, then we got 5 to 1, right? D-E-F-G-A. There's our 5 to our 1. So that's our first four measures. And then our second four measure starts and we have G flat 7, which is a 4 chord again, to our sharp 4, which is this G diminished--and I'll go over that when we get to that section--then back to our 1 chord, D flat 7, then we have a 3 and a 6, our F minor to B flat, right? D-E-F, right? So that's 3. And then D-E-F-G-A-B, 6. Then we have our ii minor, 5, 7 right there on the 9th and 10th bars. And then our 11th bar and12th bars, we wrote a 1-6-2-5 turnaround again, so you have 1-6-ii minor-5-7. So we're going to go through measure by measure and show you how to walk these different bass lines. But all these different chords all come out of the D flat major scale, so as long as you have that scale pattern down, we can walk through this whole tune like a breeze."
