A good game to help group mind and support.
Everyone stood in a circle. Eyes closed. One person stars making any sound of an instrument or any musical sound with their voice. Could be a drum, a piano, a violin, la la la. Everyone joins in and backs them up by doing the same sound. Then different sounds come and go. Some people may be being drums for a while, others are humming, others clapping. Different sounds come and go. If a new sound appears at least one other person backs them up by also making that sound. The sounds compliment each other and an ongoing soundscape is formed.
