The following quote is from the best book available on Greek dances – Traditional Dance in Greek Culture by Yvonne Hunt, 1996.
“Another dance of interest is the Tai Tai of Aidonohori. Here we find once more a dance performed during the Easter season. According to Stratou (1979:113) it is danced only the first three days of Easter – Easter Sunday, Monday and Tuesday – and closes the Easter celebration on Tuesday before the priest rings the bell announcing vespers. This is danced by both men and women in a crossed-handhold which allows the men to raise to raise their arms over the heads of the women at one point in the music, creating two lines – men and women – but still linked by handkerchiefs between the first man and woman as well as the last man and woman. It is always danced to the same tune which is sung by the dancers.”
