The Psalms are the hymnbook of our Jewish forebears. They have been an integral part of Christian worship since the beginning.
The classic method of singing Psalms at the Eucharist is the method known as responsorial. The congregation sings a repeated refrain after every two or three verses, a melody that can be easily imitated by most people when heard. A cantor, or a small group of singers, chants the verses of the Psalm in a manner that is simple, but requires some preparation.
Below are links to settings of Psalms appointed for the celebration of the Eucharist. The refrains were composed by Bishop Martins many years ago, and have been used in several parishes. The verses are pointed to very ancient and traditional “plainsong” tones, and are intended to be chanted without accompaniment.
