Balos or Ballos of Kythnos (Greek: : Μπάλος της Κύθνου or Θερμιώτικος μπάλος) is a traditional folk dance of Greece, from the island of Kythnos.
It is known for the multiple rotations of the dancing couple, the so-called "voltes" or "furles".
[1][2] It is considered as an integral part of the music and dance tradition of Kythnos, and it is performed especially during local festivals.
In a proper Kythnos' feast, balos is performed after the sirto dance.
[1][2][4] It is considered a demanding dance, the specificity of which has been pointed out by distinguished Greek musicologists and choreographers, among them Dora Stratou and Domna Samiou.
