Here it is. It was in response to a question from Banjer.

What I generally refer to as a turnaround is a two- or four-bar instrumental phrase at the end of a verse (or chorus if there is one) which serves as an intro to the next verse. This allows the audience some time to absorb what has gone before and prepare for what's coming. It also allows me to catch my breath for more singing. I will frequently use the turnaround phrase as an outro of sorts, sometimes leading up to a "big finish(tm)"
