Vexilla Regis Prodeunt

This arrangement of the venerable 6th-century chant is scored SATB choir, organ, and handbells (although only two bells are needed for the drone-like open fifth). Because this is based on a plainchant but uses modern notation, the unmetered and unpredictable note groupings will require some advance preparation by the choir, its director, and the organist to ensure proper ensemble. It is moderately difficult, but the end result is effective and worth the effort.
