- perhaps the most ancient title used by the Church to denote a piece of composed hymnography. In Greek this word means "to be obedient," "to hear," "to respond."
Presently, the Hypakoe is the particular title of a Troparion
hymn sung during Resurrectional Matins. It varies according to the tone of the week from the Octoechos and comes after the Resurrectional hymns which are sung together with the refrain from Ps. 119: "Blessed art Thou, O Lord, teach me Thy statutes."
The Hypakoe of Pascha is the one most commonly known. It is sung after the third ode of the Paschal Canon, during the Paschal Hours, and again after the Little Entrance at Divine Liturgy.
