The psalm, with refrain based on the opening line of veni emmanuel, is matched with newly composed verses: I and 3 for cantor, 2 for SATB.
A second version of the refrain has the men carry the tune, while SA voices sing a 2-part descant. The Alleluia uses the same melodic material, but here it is in rapid accented eighth notes, strikingly different from the psalm refrain.
Choral verses are given for all the Sundays of Advent.
