For most infant baptisms that I have chanted, as we process into the church after the exorcisms, the chanters chant both the Theophany Troparion "When Thou O Lord was baptized" and the Pentecost Troparion "Blessed art Thou, O Christ our God." But as this is the Paschal season, do we dispense with those troparia and instead sing the Paschal Troparion? Also, after the baptism and the during the vesting, it is customary to sing the Katavasiae of the Cross in tone 8. Should those also be dispensed with and the Katavasiae of Pascha be chanted instead?
Many thanks, O learned liturgical experts.
I've never seen a rubric indicating that anything should be chanted between the making of a catechumen and the start of the Baptism proper. We do in my parish - saying the Apolytikion of Theophany (As You were baptized in the Jordan, O Lord...) three times - but I do not think I've seen it written into any prayer books.
That said - yes, I'd probably switch to singing "Christ is Risen." I've not seen any indication that when baptisms are performed during Bright Week the hymn of Theophany (or Pentecost, for that matter) should be included. The entire week is filled with two constants: singing "Christ is Risen" many times, and singing "All those who have been baptized into Christ..." at every Liturgy. Stick with that formula, IMO.
As to your Katavasiae question: yes, switch. This is one thing I definitely
have seen - in the Priest's prayer book (actually, in two different translations of said book) they include both the Katavasiae of the Cross and of Pascha.
