3 Octaves of Handbells Level 3-Hal Hopson's hymn concertatos always offer plenty of performance options and flexibility. God of Grace and God of Glory is no exception. A triumphant majestic song of praise this octavo could be sung as a choir hymnanthem or with the congregation as a concertato. The handbells and soprano descant are optional but add power and might to this glorious choral.
