Ton Despotin

Ton Despotin is an acclamation chanted by the cantor or choir in honour of a bishop when he gives a blessing in the Eastern Orthodox or Eastern Catholic churches. While the Divine Liturgy may be chanted in any language, "Ton Despotin" is almost always chanted in the original Greek.
The words in Greek are:
An English translation would read:
The final phrase "Eis pollá étē, Déspota" is usually chanted three times, each with progressively more elaborate embellishment.
There are many musical settings for the hymn, which can be roughly divided into simple and elaborate, each being used at different points during the services. Often, "Ton Despótēn" is chanted while the bishop, vested in full, stands on an eagle rug and blesses his flock with dikirion and trikirion.
An abbreviated form, consisting only of plainchanting "Is pollá eti, Déspota" three times, is used at less solemn blessings.
