 So we're ready for a little bit more practice on finding roots and fifths, and this time we're going to add the octave into the pattern that we play as we play through the changes on blues by five. So we're just going to continue using our B-flat as our root, our F as our fifth, and then we're going to add the octave in, and we're going to add it into that pattern as we go through the tunes. So we'll have four measures of the B-flat, root, fifth, root, fifth, root, fifth, root, fifth. Then we're going to go to the E-flat, root, fifth, root, fifth. Back to the B-flat, root, fifth, root, fifth. Then we're going to go up to the F chord, root, fifth, root, fifth. Back to the B-flat, root, fifth, and then to the F again, root, fifth, and we get back to the beginning of the tune. Okay? Let's put the drums on and let's run through that. Here we go. Up the tune, B-flat, B-flat, fifth, root, fifth, root, fifth, root, fifth, E-flat, root, fifth, root, fifth, B-flat, root, fifth, root, fifth, F, fifth, root, fifth, B-flat, root, fifth, F, root, fifth. of the tune, B-flat, 5th root, 5th root, 5th root, 5th E-flat, root, 5th root, 5th B-flat, root, 5th root, 5th F, root, 5th root, 5th B-flat, root, 5th F, root, 5th top of the tune. that and get really good at playing that root in both octaves and that really gives you some variation in the tune.
