The Serra (Pontic: Σέρρα) is a Pontic Greek war dance of ancient Greek origin,[1] from the Pontus region of the Black Sea.
Its name comes from the Serra river, in the region of Trapezounda.
It is also called Pyrrhichios (Greek: Πυρρίχιος).
The rhythm starts in 716 and becomes an even meter when the dance speeds up.
The Pontic Lyra often accompanies this dance.
