Dechrau Canu, Dechrau Canmol is a television series featuring congregational Christian singing in the Welsh language. Currently aired by the Welsh television channel S4C, it is one of the longest-running television programmes on any British television channel, the first edition having been broadcast by the BBC from Trinity Chapel, Swansea, in 1961. The programme inspired the creation of the similar English-language series Songs of Praise, which began later in the same year.
The programme was revamped in September 2006 with a new and diverse team of enthusiastic presenters, including Martyn Geraint. A series now consists of forty programmes lasting half an hour each and three special hour-long programmes.
The programmes celebrate important festivals and dates in the Christian calendar and place on film the celebration of important national and international occasions where the music is of a devotional and religious nature.
