Remember the question from Lesson 3? What note to you didn't sound as good as the others on the Mixolydian Mode? If you thought it was the 4th note of the scale, you would be correct. I'll explain more later, but be aware of the fact that a 4th on a Mixolydian Mode (used on a Dominant 7th chord) wants to resolve down to the 3rd. Therefore hanging out on that 4 can be tricky, and... dissonant. There is nothing particularly wrong with dissonance, but only when YOU are in control of it.
That being said, let's jam on the mixolydian mode, which sounds rather bluesy and not major or minor. In fact, most blues are predominately based on mixolydian modes, along with another scale known as the blues scale, which we will cover later. For now, play on this tune based on ONE mixolydian mode, entitled "Mix It Up"
OK, now that you are all mixolydian masters, it's on to the next level. I'm sure you have heard the phrase ii-V-I thrown around a time or two. Right? Well, if you haven't, this is your first throw. So to continue with the wonderous two-five-one, in all it's circle of 4th glory, go on to Lesson 5. Now! What are you waiting for? Just do it already.
