The participants stand in a circle, then the facilitator will sing in a very weak whisper:
Da tudu tudita.
It’s not loud enough.
We can make it louder.”
The facilitator will stop at each verse, then the participants repeat verse by verse with the same tone. Each time the song is completed, the facilitator will repeat it by increasing the volume, eventually screaming at the top of his/her lungs.
(This energizer emerged in a French Rugby team that used the song to motivate themselves before a game.)
