Isios is the most popular dance of the Island of Kalymnos. The Isios Horos (meaning straight dance) as it is called by the locals is done at every social gathering and festivity. It is danced in an open circle and is danced by both men and women. The rhythm is 2/4 and the hand hold is in a basket weave formation. Only the leader improvises on the steps of the dance, the rest of the dancers follow through with the basic step.
