This music is a set of variations on the tune known as St Magnus, which is attributed to Jeremiah Clarke. Most people will associate it with Thomas Kellys hymn which begins: The Head that once was crowned with thorns is crowned with glory now. The tune is very simple, consisting of just two, four-bar phrases. Neither is there much in the way of rhythmic variety, every note being a crotchet with the exception of two quavers, and the last note in each phrase. Within such a simple structure, however, lies considerable strength.
