RYAN LARSON: So now, we're going to go through and analyze the chord changes to "Mack the Knife." And it's nice that the chord changes stay right in the major scale, right? So we start on D flat major, so our I Major for two measures, and then we have E flat, so right? D, E. So there is our 2 chord for a measure, then A flat, so right? D, E, F, G, A, our 5 chord, for a measure. So 1-2-5 then again 2-5-1, and then we go on to our third, real quick, here at the end which leads to the bridge, right? D, E, F, right? There is our 3 chord, then we have B flat, so D, E, F, G, A, B flat. So there is our vi minor. So it's that easy. Notice I'm not counting the flats or the sharps. They'll give that information to you. All you really have to do is get up to that note and alphabet, and don't worry about it. So B flat minor for two measures, then E flat minor, our 2 chord, again for two measures. Then we've got E flat, A flat for a measure then your 1-6-2-5 turnaround, right? One-6-2-5. So you want to go through and maybe pause the computer screen and write this chord progression down. It's a 16-bar chord progression, and we're going to go it by section by section, so you really want to write it down, analyze it and then go through. And we'll show you how to walk through on the bass in D flat for the whole tune.
