We're talking about Synchronized Skating teams talking during a competition program. That is, one or more skaters calling out the count or steps of a move, in order to keep the team together during the program.
It can be as simple as: AND; 1,2,3,4,5,6,7,turn, or calling out the actual steps like; Chasse Left, Chasse Right, Heads to pivot, 1,2 mohawk.
It isn't easy when you are concentrating on your own skating (I'm usually the one out of line when doing it), but it does help keep the team together.
I also run out of puff sometimes, but then in practice I'm usually shouting.
Here's another thing; what to do when you appoint someone to call a move, and they call out of time with the music? I am in that situation.
