Greek dances
Greek dance ("horos") is a very old tradition, being referred to by authors such as Plato, Aristotle, Plutarch and Lucian. There are different styles and interpretations from all of the islands and surrounding mainland areas. Each region formed its own choreography and style to fit in with their own ways. For example, island dances have more of a different smooth flow to them, while Pontic dancing closer to the Black Sea, is very sharp. There are over 10,000 traditional dances that come from all regions of Greece. There are also pan-Hellenic dances, which have been adopted throughout  the Greek world. These include specifically the Syrtos, Kalamatianos, Pyrrhichios, Ballos and hasapiko. Traditional Greek dancing has a primarily social function. It brings the community together at key points of the year, such as Easter, the grape harvest or patronal festivals; and at key points in the lives of individuals and families, such as weddings. For this reason, tradition frequently dictates a strict order in the arrangement of the dancers, for example, by age. Greek dances are performed also in diaspora Greek communities among international folk dance groups. In Ancient Greece, dance was a form of ritual, as well as  a pastime. Dance could be included in hunting communities, initiation ceremony rituals of age, marriage, and death, entertainment, dance festivals, and religious activity. It was also viewed as a way to educate children about social norms and morals, and was viewed as being essential for physical and emotional development. Dance was used in regard to war as a form of military training, as well as a ritual that served as a mediator between the gods and humans. What modern times may consider a parade, military drill, funeral, children’s game, these were seen as forms of dance as long as  they were meant to be an exhibition of a rhythmic performance. Suda mention an ancient Greek dance which was called Dipodia (Διποδία), meaning two-step/two-footer. Modern and regional dances. Aegean Islands.

Greek Orthodox Folk Dance & Choral Festival (FDF). Since 1976, the Greek Orthodox Metropolis of San Francisco has held a convention that allows Greek Dance groups from various churches in the Pacific Region of the United States to compete. Up to 3,000 people participate annually and it is described as the largest  youth ministry program in the Metropolis of San Francisco. Within the competition, there are four divisions, two of which are judged and two of which are exhibition suites. Division I and Division II are judged by a table of judges who have done years of research in Greece and instructed others on the styling and other important elements of Greek dancing. Each competing team will be placed into a division and group based on the average age of the team. Each team performs two times and perfected suites that can be from many places in Greece (islands, mainland, villages) and  feature many different dances. The judges will score the teams based on their costumes, singing, stage presence, styling, and how closely it resembles the region that their suite is from.
