 You do a listening exercise that we made up that goes around in a circle where one person plays a phrase, do, do, do, do, and then the other person compliment it. So it's do, do, do, do, pa, pa, pa, do, do, do, pa, pa, pa, do, do, do, or somebody do, do, do, boo, boo, boo, do, do, do. And when it comes together in a pattern, all the four band members say the word, hey, they say, hey, and that means I'm listening to you.
