Here are the Hymn Tune Introits for Epiphany (Vigil and Feast). It seems that when a separate Introit for the Vigil was appointed in the new Roman Missal, there was no corresponding designation of the associated Psalm verses. It was suggested that, until such time as this is remedied, one simply uses the same verses as used for the Feast itself, which is what I've done here (making it possible to set both Introit texts (as versified by Kathy Pluth) together. When and if a separate set of Psalm verses is appointed for the Vigil, then I'll make the necessary modifications.\

The Hymn Tune I chose for this is PUER NOBIS NASCITUR, which I harmonized with largely stepwise motion in the lower parts (especially the bass line).
