In part three of our walking bass series, we are looking at the final changes for the 12 bar blues.
In Lesson 2, we continued to build patterns for the common chord progressions we see in blues. So far we have patterns for each chord change in the 12-Bar Blues except for one, moving from V to IV (i.e. G7 to F7).
Examples 1 and 2 demonstrate patterns for moving from V to IV, which can also be thought of as descending a whole step. It is an integral part of playing the blues, where the V chord descends to the IV chord in bars nine and ten.
Examples 1uses only chord tones and descends chromatically to the root of the F7 chord.
Walking Bass Blues Examples
Example 1: [1-5-1-b7]
Example 2 is the first half of the boogie pat-tern that we developed in Lesson 2, this time over a G7 chord.That pattern took us up to the b7th and back down to the root, however in this case, the b7th (F) is as far as we need to go.
Example 2: [1-3-5-6]
In Example 3, we apply some of the patterns we’ve learned to a 12-Bar Blues progression in the key of C. See if you can identify each of the patterns we’ve learned, especially when they are applied to different chords. For example, we looked at C7 to G7 for the I to V movement, but these patterns are also applied to the F7 to C7 movement from bar 2 to bar 3, bar 6 to bar 7 and bar 10 to bar 11.
Example 3: Twelve-Bar Blues:
From this example, you can see that we can easily create a smooth, functional walking bassline just by linking together a handful of patterns over four different chord changes: I to IV, Static, I to V and V to IV.
Substitute some of the other patterns that we have learned into this progression, and see how they sound. Some patterns will sound better to you than others, so focus on the pat-terns you like the most. I recommend memorizing three patterns for the I to IV progression to get started, since it is the most common, and only one or two for the other chord chang-es. Once you have picked out a few patterns you like, apply them to the 12 Bar Blues like we did in Example 3, and MEMORIZE that entire 12 bar bassline. Having a go-to, “scripted” bassline for the blues will give you a good template to build off, as well as a solid line to fall back on.
