Canon of the forefeast, with 6 troparia, including its irmos; and those of the Triodion, in their order.
Alleluia, and the trinitarian hymns of the tone.

Today the first-fruits of universal joy command us to chant hymnody of the forefeast; for, lo! Gabriel cometh, bearing a salutation to the Virgin, and he crieth out to her: “Rejoice, O thou who art full of grace! The Lord is with thee!”
The appointed kathismata, and the rest, as usual.
