Caniadaeth y Cysegr

Caniadaeth y Cysegr is a religious radio programme of congregational hymn-singing, produced in the Welsh language by BBC Radio Cymru. Traditionally broadcast on a Sunday afternoon, it comprises recorded excerpts from Cymanfaoedd Canu (plural of Cymanfa Ganu or Singing Festival). Largely amateur singers sing in four voice harmony on this program. Each edition is available on the BBC's Listen Again feature on its website.
