Musica Scotica Vol VIII: Robert Johnson - O Eternal God [download]

Edited by Elaine Moohan and Kenneth Elliott.

O eternal God (for four voices, MScTB) appeared in Day’s Certaine Notes (1560). It is written in the four-part chordal style that was to become standard for Psalm and Canticle settings and almost certainly dates from the late 1540s.
