B.B. King (CD1, Tk5)
Ive Got My Mojo Working
rhythm and blues/twelve-bar blues (recorded in 1956)
lyrics by Muddy Waters
B.B. King, guitar and vocals; ?, horn ensemble?

At the time of early rock and roll, the blues had moved to a harder driving blues using electric guitar and a shuffle rhythmic beat. Rhythm and blues at this time was very different from R&B as defined by artists of the twenty-first century. The move from the sound of Delta blues to a more sophisticated ensemble sound came quickly and was advanced by performers like B.B. King. Notice the addition of a horn section, whose players are probably improvising many of the background licks filling between the vocal phrases. Call and response is still a vital part of the musical texture. B.B. King stayed true to the twelve-bar blues. Notice how the words of this song give it a larger structure. It has a feeling of verse and chorus even though it does not leave the twelve-bar blues structure. The typical twelve-bar blues usually has the same text for the first two phrases and a new punch line third phrase; however, in this song the second phrase almost always uses the title of the song and then moves on.
