Watch the Shuffle in G online guitar lesson by David Santos from 50 Bass Grooves You MUST Know
This song demonstrates that not every blues song will be conceived and realized in the form of a standard 12 bar blues. Often a song is written with a blues form in mind while altering it to fit the composer’s vision. In Shuffle in G a bass line is stated for the G7 chord for 8 bars, and the same motif continues on the C7 chord for 6 bars. A turnaround, which is devised of an Eb7 chord for two bars, and a D7 chord for two bars, is then utilized. A quarter note triplet is employed on the D7 chord as a rhythmic device to return to the G7 chord. The band then vamps for 12 bars on the G7 and ends on a sustaining whole note.
