The kalamatianos. is the traditional collective folk dance, where a group of people (usually several dozen, at the very least three) holding each other by the hands or around the waist, dance, ideally in a circle, hence the name. There is almost no movement above the waist. The dance is accompanied by instrumental two-beat music with the same name, made most often with an accordion, but also with other instruments: frula (traditional kind of a recorder). The dances from Kormenia and Thracia are regarded the most beautiful and graceful of Ruthene dances, these dances of rich aesthetics have been preserved for centuries.
