Vespers – Deus in adiutorium

I’m quite often asked ‘What is Vespers?’  Vespers is a one of the liturgical Hours or "offices" that are celebrated at defined moments of the day. The word comes from Latin ‘vespera’ which means ‘evening’ and the office of Vespers was held1 between 5 and 6pm (17:00 – 18:00). Vespers followed a strict pattern:

1: Opening Verse
Deus in adiutorium (O Lord, make speed) –  the text of Psalm 69:2 in the Vulgate .
2: Psalms
The opening verse was followed by five psalms
3: Reading
A reading of a lesson or of a capitulum (a short reading in the Liturgy of the Hours)
4: A hymn
The choice of hymn was defined by the time of year and local practice.
5: Magnificat with antiphon
The Magnificat followed by seasonally appropriate antiphon.
6: Prayers
Prayers appropriate to the time of day combined with prayers appropriate to the time of year and local practice.
7: Benedicamus Domino
Benedicamus Domino (Let us bless the Lord")

This rigid pattern coupled with the fact that the chants were so well known presented considerable challenges to composers who needed to integrate their polyphonic music into this fixed framework in a way that created musical interest for the congregation. Many composers composed settings for Vespers either in whole or in part some using the chant which you can hear below as cantus firmus.


Deus in adiutorium meum intende

Deus in adiutorium meum intende.
Domine ad adjuvandum me festina.

(Septuagesimae ad Pasqua loco alleluia: Laus tibi Domine Rex aeternae gloriae.)

O Lord, make speed to save me:
O Lord, make haste to help me.

(in penitential season alleluia replaced by: Praise to you, O Lord: King of eternal glory.)

Gloria Patri, et Filio, et Spiritui Sancto.Glory be to the Father, and to the Son, and to the Holy Ghost:
Sicut erat in principio, et nunc, et semperAs it was in the beginning, is now and ever shall be,
Et in saecula, saeculorum, Amen.
World without end, Amen. Alleluia.
