In this weeks class we worked on attaching a turnaround to the matchbox blues rhythm shuffle. To do that, you go thru the normal 12-bar blues progression, 1-1-1-1-4-4-1-1-5-4-1-5, but on that last "1", only do a single beat of the 1, then do the turnaround (see turnaround section of the blues materials)which then leads back to the beginning of another blues shuffle.
