The recording features instruments commonly depicted in nativity scenes, such as the lute, harp, and rebec (an early bowed string instrument similar to the violin).
During the period from the 14th to the 17th centuries, sacred and secular elements in Christmas celebrations were intertwined, before the influence of Puritanism.
The album's title, "Christus Natus Est," is taken from the plainsong Respond at Matins and processional Respond at Mass on Christmas Day, "Verbum caro."
The medieval carols on this album often show a dance structure, with a 'burden' (chorus) alternating with verses sung by solo voices.
The carol "Remember O thou man" survived in popular usage long enough to be quoted by Thomas Hardy in his novel "Under the Greenwood Tree."
The original meaning of 'carol' was 'round-dance,' and later 'joyous song,' often involving physical movement or processions.
