In time for Christmas, we are making available the Dominican Chant for the Genealogy of Jesus Christ According to Matthew, found in the appendix to the Missale Ordinis Praedicatorum. Traditionally part of the Office of Matins for Christmas, when it is sung after the last Responsory, the Genealogy may also be used with the modern Liturgy of the Hours. According to the Proprium Officii Ordinis Praedicatorum (1982), p. 682, it may be sung after the second Responsory of Office of Readings, especially when this Office is sung just before Midnight Mass, or it may be transferred and sung in place of the Short Reading at First Vespers of Christmas.
The chant may be downloaded here, or from the left sidebar at Dominican Liturgy.
