The blues form is ubiquitous in [[jazz]], [[rhythm and blues]], and [[rock and roll]], and is characterized by the [[Call and response (music)|call-and-response]] pattern, the [[blues scale]], and specific [[chord progression]]s, of which the [[twelve-bar blues]] is the most common. [[Blue note]]s (or "worried notes"), usually thirds, fifths or sevenths flattened in [[Pitch (music)|pitch]], are also an essential part of the sound. Blues [[shuffle note|shuffles]] or [[walking bass]] reinforce the trance-like rhythm and form a repetitive effect known as the [[groove (popular music)|groove]].
