Talkin' Blues: Pedal-Point Licks

pedal point is a single note sustained (or repeatedly articulated) against a moving melody. It adds dimension to a melody by highlighting its “push and pull” against a central note, which is usually, but not exclusively, the tonic of the key or root note of a chord. In blues, perhaps the best-known example of a pedal point is the main theme of Stevie Ray Vaughan’s solo on “Cold Shot,” which is itself reminiscent of Buddy Guy’s “Leave My Girl Alone,” Lonnie Mack’s “Why” and, before them, bluesy Hammond organists who would sustain a note with one finger while riffing with the other hand.
