A polychoral triptych – in three Parts or sections – for 25 voice-parts (SSSSSSAAAAAATTTTTTBBBBBB plus cantus firmus) and a total duration of 25 minutes. The original early 16th-century canon – Jesus autem transiens / Credo in Deum – is a setting for 13 (i.e. 1 + 12) voices of the Apostles' Creed in which each of the 12 Apostles' names are assigned to each phrase. "Jesus autem transiens" means "Jesus passing through them" and so the plainchant motif with these words is repeated as each of the twelve Apostles takes up the story of the Creed. In Transiens the music of the original canon is expanded for another 12 voices, making 25 in total (i.e. 1 + 24), and taking inspiration from the scene in the Book of Revelation of 24 elders singing a "new song" around the throne of the Lamb. The central Part of Transiens is an ethereal arrangement of the original, while the outer two Parts focus on the 12 phrases from the Creed (some longer, some shorter) and treat each as a canon by itself, interspersed by echos of the complete original and new superimpositions of the underlying 9-note theme of Jesus autem transiens. There is a direct quotation of the hymn sung by the old man in Gavin Bryars's Jesus' Blood Never Failed Me Yet, for which Transiens was written as a companion piece. The world première recording by The Song Company, Australia's national vocal ensemble, with the University Of Western Australia Conservatorium Of Music and The Oriana Chorale is available digitally and on limited edition transparent red vinyl: https://www.hyperion-records.co.uk/dc.asp?dc=D_1EMBOT https://music.song.company/album/burden-of-truth https://soundsoftheuniverse.com/product/-gavin-bryars-jesus-blood-never-failed-me-yet-antony-pitts-transiens
