Just as the psalms were at the heart of worship in Jewish temple and synagogue, so music has been central to Christian worship since its beginning. Right through medieval times and the centuries since, some of the most creative musical geniuses have produced works to be performed as part of the life of the Christian church. The result is a great wealth of hymns, anthems, oratorios and other sacred music, from the direct and simple to the most ornate and complex. And from this rich store, organists and choirmasters in churches, chapels and cathedrals throughout the world draw hymns and other music for worship today.
