Bryn Calfaria is a Welsh hymn tune written in 8,7,8,7,4,4,4,7,7 meter. The melody, written by William Owen, is used as a setting for several hymns, most notably the English "Lord, Enthroned in Heavenly Splendor" and the Welsh hymn "Laudamus". The tune is reputed to have been originally written by Owen on a piece of slate whilst on his way to work at the Dorothea Quarry in Gwynedd, North Wales.[1]
