Resonet in laudibus

"Resonet in laudibus" (Latin for "Resound in praises") is a 14th-century Christmas carol which was widely known in medieval Europe, and is still performed today.

[1] Although probably earlier, in manuscript form it first appears in the Moosburg gradual of 1360 and occurs in several 15th, 16th and 17th century printed collections from both Catholic and Lutheran traditions.

[3] Georg Witzel, a contemporary of Martin Luther, referred to the carol as "one of the chief Christmas songs of joy" in 1550.

[4] The Lutheran poet and composer Johann Walter wrote one of his finest motets using this song.

Sir David Willcocks' arrangement in Carols for Choirs 2 titles the work "Resonemus laudibus".
