The polyphony of this Mass […] was beautifully sung by Cantus Magnus under the direction of Matthew Schellhorn: his generous artistic contributions in the field of Sacred Music are of true value in upholding the dignity of the Sacred Liturgy
Bishop Athanasius Schneider O.R.C.
Cantus Magnus is a small professional vocal ensemble founded in 2011 by Matthew Schellhorn
to provide polyphony and chant for celebrations of the traditional Latin Mass (also known as the usus antiquior
or Extraordinary Form of the Roman Rite). In this way, the group fulfils its objective of performing sacred music in the context for which it was composed – the worship of God during Solemn Mass.
The group regularly provides music for special events and pilgrimages organised by The Latin Mass Society of England and Wales, including the annual pilgrimages to Aylesford and Walsingham. Cantus Magnus also sings frequently at Masses arranged by Juventutem London, a Catholic organisation for young people with a love of traditional liturgy.
Since 2012, Cantus Magnus has provided the music for the Sacred Triduum held at St Mary Moorfields, London. In 2014, it gave the UK premiere of the Tenebrae Lamentations and Responses by Italian cleric and composer Pietro Amico Giacobetti (fl. 1579–1616).
Cantus Magnus led the music for the 2013 and 2015 General Assembly of international group Foederatio Internationalis Una Voce in Rome; on the latter occasion it also assisted with the events of the Populus Summorum Pontificum, singing the Mass in several churches including Santissima Trinità dei Pellgrini and St Peter’s Basilica.
In 2018, Cantus Magnus provided music during the visit of His Excellency Bishop Athanasius Schneider to London.
