To hear colonial Christmas music, you could go to Williamsburg with your loved ones, or you could go to the Folger Shakespeare Library and hear the music of the Iberian colonies. The Folger Consort’s annual holiday concert revolves around the idea of “Christmas in New Spain.” Its 10-day run concludes this afternoon, and the songs and liturgical works you’ll hear are the same you might have heard on the streets of Guatemala during the 1600s or at an 18th-century mass in Peru. Six musicians and six singers collaborate to perform arrangements of pieces preserved in century-old manuscripts. So no, you won’t hear “Greensleeves,” but you will get a sense of what music, to the ears of an early Latin American colonial composer, seemed worthy of gold, frankincense, and myrrh. The Folger Consort performs Dec. 13–22 at Folger Elizabethan Theatre, 201 East Capitol St. SE. $50. (202) 544-4600. folger.edu.
