The Demo Team I train do routines similar to a shncyronized poosae, but more flare (no music, just enegery). We also do breaking with basic hand movements to advanced kicks, self defense and weapons. Not only is the team the demonstrationteam but they are also the competition team.
Demo team works hard every friday night and saturday morning to help inhance the studio's precense and thier own skills. The kids I teach are talented and have a lot of heart. That's what makes my demo team.
In terms of orginazaiton you should have a written plan of what you want and expect. Consult with demo team members and of course your master. This is in order to help make a team that represents the studio best.
