In baseball, the pitcher and catcher better know what the other is likely to do. If you’re a pitcher and throw the wrong pitch, what you don’t want is for the catcher to have to wait for it to stop rolling before he picks it up. 
That’s why they use signals.
All team shows should, too. If you don’t, you’re not going to be as cohesive as you’d like to be. A simple “point at me as you’re saying your last word” leads to instant communication, effortless momentum, and being “tight” but not stepping on each other.
Two other signals:
- Hold your hand up and point to yourself = “Come to me.”
- Hold your hands up over your face = “Do NOT come back to me. I have nothing.”
This is a foolproof way to sound better.
It’s amazing how many teams have told me “We don’t need signals.”
Yes, you do. Make it easy for yourself and for your partner.
