The significance of plainchant to the monks of Glenstal Abbey.

Glenstal Abbey is home to a community of Benedictine monks in Murroe, County Limerick. The monks assemble together for prayer several times a day, and plainchant, a body of chants used in the liturgies composed in Latin text, plays a significant part. They also run a boarding school for boys, a farm and a guesthouse on the abbey site.

Dom Bernard O'Dea OSB (Order of Saint Benedict) explains that the origins of plainchant are probably Grecian and Hebraic. He believes the 9th and 10th century were the golden age of plainchant.

When it comes to a solemn feast, we all feel more at home with plainchant.

While they make concessions for the boys attending their school, the monks frequently use plainchant. On the greater feasts such as All Souls Day they have a completely Latin liturgy.

Accompanying scenes of Glenstal Abbey and its surroundings, the monks sing two plainchant pieces from mass and the liturgy for All Saints Day. The opening is joyous while the offertory is quieter and perhaps more meditative.
