Michael Praetorius’ In dulci jubilo is a gloriously expansive amalgam of sound and text. Composed near the end of Praetorius’ life as part of his Polyhymnia Caduceatrix et Panegyrica (Polychoral Hymns of Peace and Festivals) of 1619, this setting of the well-known tune In dulci jubilo was actually his 11th, and most ornate.
