Nijemo Kolo is a Dalmatian closed circledance performed by communities in southern Croatia exclusively without music, although vocal or instrumental performances may precede or follow it.
It galvanised a tired end-of-festival audience into forming, spontaneously, a giant dance circle joining hands being a Celtic form of applause that is as common as clapping.
Under a bright full moon, dozens of young, unmarried village women gather in a circle, join hands and sing and dance all night under the direction of a lead singer.
