Okay, let's look at the blues bass line. There is one bass line that, maybe you've even heard before, but this is the popular blues bass line. This is the prototype on which its based. Let's say we're in the key of A seven, we're playing the A seven twelve bar blues. The first thing we'll be outlining is an A seventh. But we're going to only get to a certain point with it. We have four beats, 'cause it's in one measure, and we're in four-four. We're playing quarter notes. So we're going to play, A, C sharp, E, and then the sixth scale degree of an A major. Or an A dominant even. The F sharp. A, C sharp, E, F sharp, which happens to be the third scale degree of our D seven. D, which is the next chord, our four-seven. D, F sharp, A, B, so, A, C sharp, E, F sharp. Make sure you're alternating these fingers over here to get a good swing sound. D, F sharp, A, B.
