The penitent nature of this 10th-century text chant makes it perfect for Lenten listening. It is unknown who penned the original prayer, but it is believed to have Mozarabic origins. The hymn is not part of the texts of the liturgy, and would instead be sung during Communion or as a recessional hymn.
This arrangement was produced by Marco Frisina, in 2011. Frisina injected the originally Gregorian style with polyphony, giving each voice a distinct melody to sing. These voice parts all combine into a melody as a whole. The use of dynamics create an almost ethereal effect, aided by the obviously high ceilings of the recording space.
Translated Lyrics:
Hear us, O Lord, and have mercy, because we have sinned against Thee. Hear us, O Lord, and have mercy, because we have sinned against Thee. To Thee, highest King, Redeemer of all, do we lift up our eyes in weeping: Hear, O Christ, the prayers of your servants. Hear us, O Lord, and have mercy, because we have sinned against Thee. Right hand of the Father, corner-stone, way of salvation, gate of heaven, wash away our stains of sin. Hear us, O Lord, and have mercy, because we have sinned against Thee. We beseech Thee, God, in Thy great majesty: Hear our groans with Thy holy ears: calmly forgive our crimes. Hear us, O Lord, and have mercy, because we have sinned against Thee. To Thee we confess our sins admitted with a contrite heart We reveal the things hidden: By Thy kindness, O Redeemer, overlook them. Hear us, O Lord, and have mercy, because we have sinned against Thee. The Innocent, seized, not refusing to be led; condemned by false witnesses because of impious men O Christ, keep safe those whom Thou hast redeemed. Hear us, O Lord, and have mercy, because we have sinned against Thee.
