De cora lux mj 134 (1980)
Each of the three verses of this plainsong hymn associated with the feast of St. Peter and St Paul on 29th June, De cora lux, is passed in turn between three vocal lines. The style of the music imitates early 14th century Italian sacred works which use complete plainsong melodies sung at normal speed rather than drastically slowed down and treated as a cantus firmus. In this way, interest passes to the texture and harmony rather than polyphony. Only the part singing the plainsong has a text.
