Blues incorporated spirituals, work songs, field hollers, shouts, chants, and rhymed simple narrative ballads. The blues form, ubiquitous in jazz, rhythm and blues and rock and roll, is characterized by the call-and-response pattern, the blues scale and specific chord progressions, of which the twelve-bar blues is the most common.

Blues shuffles or walking bass reinforce the trance-like rhythm and form a repetitive effect known as the groove.  - Hezekiah Leroy Gordon Smith (August 14, 1909  September 25, 1967), better known as Stuff Smith, was an American jazz violinist.
