Among the most beautiful chants of the Dominican Office of Tenebrae (Matins and Laudes on the days of the Pascal Triduum) are the responsories used with the Lamentations and other readings. By provision of the Proprium Officiorum Ordinis Praedicatorum (1982), these may also be used with the modern Liturgy of the Hours. This excellent video, made available by Bro. Lawrence Lew, O.P., shows the friars of Blackfriars Oxford chanting the responsories Velum Templi and Tradiderunt Me, as well as the Benedictus (in English).
We at St. Albert the Great Priory in Oakland have also been celebrating Tenebrae, but, unfortunately, I have no videos or recordings.
May these beautifully performed chants inspire other Dominican communities to take advantage of the chant treasures of the Order approved for use with the Liturgy of the Hours.
