Ordo notes for Matins in the week of the Sunday after Ascension

The notes below are intended to help in finding or adapting the texts and chants for Matins according to the 1962-3 rubrics.

Sunday after the Ascension

The invitatory, hymn and responsories are as for the feast of the Ascension, and so can be found in the Liber Responsorialis for the feast.

The antiphons (Alleluia) are as for Eastertide, and the versicles are of the Ascension (both can be found in the Standhofe Psalterium).

Note that the psalms are the normal ones for a Sunday (ie Psalms 20-31) - Divinum Officium provides  a festal set of psalms instead.

The readings and responsories can, as usual, be found on the Lectio Divina Notes blog.  Chant sources for the responsories are also listed here.

The 'Ordinary' of Ascensiontide

Once upon a time, the feast of the Ascension warranted an Octave.  This was, alas, abolished, so the psalms and antiphons each day are of the day of the week, but many of the other texts used are preserved in the 'Ordinary of Ascensiontide'.  For Matins:

• the invitatory antiphon is as for the rest of Eastertide, viz Alleluia, alleluia, alleluia, alleluia;
• the hymn is Aeterne Rex Altissime (written out in full in the Liber Hymnarius, pp92-4;
• the versicles after the psalms in the first Nocturn are of Ascensiontide (in the psalter); 
• the one reading becomes Hebrews 6:18-30 with short responsory 'Dominus in caelo' (not on Divinum Officium); and
• the chapter verse is Revelation 5:12  with versicle 'Exaltare Domine'.

I will put the reading, responsory, chapter and versicle up on Lectio Divina Notes blog in time for their use.

Vigil of Pentecost

The Vigil is as for a day in Ascensiontide, but with three readings and a collect for the day.
