Cantor scores for the Lumen Christi Missal have now been posted for the Feast of the Holy Family, and for the Solemnity of Mary, the Holy Mother of God:
These scores utilize the new translation of the Roman Missal, and cover all five propers (Entrance Antiphon, Responsorial Psalm, Alleluia and Verse, Offertory Antiphon and Communion Antiphon), and are at times carefully shortened to allow for the brevity that is needed for congregational singing. The content of the Lumen Christi Missal has been approved for liturgical use by Bp. Thomas J. Olmsted, Bishop of Phoenix, and was published with the authority of the USCCB Secretariat for Divine Worship.
I also noticed this morning that CanticaNova has taken notice of the antiphons of the Lumen Christi Missal, and has begun listing them in their liturgy planning pages.
