Orlando Gibbons - Song 1 - A Prelude by Rosie Bonighton - followed by a harmonised verse.

Today this hymn melody is associated with two texts, 'Eternal ruler of the ceaseless round' and 'O Thou who at Thy Eucharist didst pray'
Orlando Gibbons’ exquisite tunes and rock-solid bass-lines for the first English hymn-book, Hymnes and Songs of the Church (1623), were written to be sung and played both at home and in church. In every case wrote only the melody and bass and four part harmonisations are thus the work of subsequent editors and editions though his bass lines leave no doubt as to the implied harmony

A Music graduate of the University of Melbourne, she also completed a Master of Arts degree in Composition at La Trobe University.

Orlando Gibbons (bapt. 25 December 1583 - 5 June 1625) was an English composer and keyboard player who was one of the last masters of the English Virginalist School and English Madrigal School. The best known member of a musical family dynasty, by the 1610s he was the leading composer and organist in England, with a career cut short by his sudden death in 1625. As a result, Gibbons's oeuvre was not as large as that of his contemporaries, like the elder William Byrd, but he made considerable contributions to many genres of his time. He is often seen as a transitional figure from the Renaissance to the Baroque periods.
