Watch the Texas Shuffle online guitar lesson by David Hamburger from Blues Alchemy
Slippery, sliding ninth chords have been a staple of Texas blues since the pioneering work of T-Bone Walker in the 1940s and 1950s. In a sense, every modern blues guitarist can trace their musical DNA back to Walker, who punctuated his sly, urbane vocals with horn-like chord hits and impeccably phrased, jazz-tinged licks. You can hear Walker's direct influence on both B.B. King and Chuck Berry, and if you think about how many guitarists they influenced in turn, you begin to get the picture.
