In music, the V-IV-I turnaround, or blues turnaround is one of several cadential patterns traditionally found in the twelve-bar blues, and commonly found in rock and roll.
Most turnarounds can also be used as intros or endings. This is because the turnaround in bars 11 and 12 takes us back (turns around) to the start of the next 12 bars of music or pulls us toward the I chord for a big finish. The intro does the same thing by kick starting the song to begin at the first cycle of 12 bars.
There are probably as many variations for the turnaround as there are blues progressions, ranging from the very simple to complicated jazz blues lines. No matter how simple or complicated a progression is, there are some basic structural guidelines that should always be applied to a turnaround.
