From Alpine churches to Nordic candlelight
In Germany, carols (Weihnachtslieder) are often sung at Adventskranz (Advent wreath) gatherings each week and on Christmas Eve around the tree. Classics like "Stille Nacht" (Silent Night) and "O Tannenbaum" are German in origin and still sung in German churches and town squares with gusto – often accompanied by brass ensembles (a beloved practice of German and Austrian folk culture).
Germany also has charming regional carols; for example, "Still, still, still" is an Austrian lullaby carol that hushes one's heart. Carol services per se (with lessons) might be less formal in Germany, but church concerts and community sings are common.
In France, the tradition of "Le Réveillon" (late-night Christmas Eve dinner) is sometimes preceded by carols at church earlier in the evening. The French have beautiful carols like "Il est né, le divin Enfant" and "Les Anges dans nos Campagnes" (Angels We Have Heard on High). A Francophone carol service will include those, perhaps alongside readings en français from Isaiah and Luke.
In French Canada, the Noël carols have a folk lilt – e.g. "Huron Carol" (the first Canadian carol, written in the Huron/Wendat indigenous language in 1642, later translated) is often sung.
Moving north, Scandinavia adds its own light. In Sweden, a highlight of Advent is St. Lucia's Day on December 13, when a girl dressed as Saint Lucia with a candle-lit crown leads a procession of maidens and "star boys" singing carols like "Santa Lucia" (an Italian melody with Swedish words) and "Natten går tunga fjät".
This merges into the carol service sphere because many churches hold Lucia carol concerts with a choir in white gowns carrying candles – an absolutely magical sight in the winter darkness. Swedish and Norwegian carols often sound like lilting folk tunes; "Deck the Halls" actually comes from a Welsh melody, but similar dance-like carols exist in Nordic lands.
In Eastern Europe, carols (often called koleda in Slavic languages) are strongly tied to folk customs. In countries like Poland and Ukraine, carols are sung not just at church but also door-to-door by carolers visiting homes – similar to old wassailing.
Ukraine gave the world the melody of "Carol of the Bells" (originally a New Year's song "Shchedryk"). A Ukrainian Christmas service will feature beautiful a cappella choral pieces, since Eastern Orthodox liturgy is traditionally unaccompanied. Imagine resonant harmonies of an Orthodox choir singing an ancient Kievan chant for the Nativity, then perhaps a lively folk carol at the end.
In Greece, the tradition of children going around on Christmas Eve playing triangles and singing carols (kalanda) to neighbors is still alive – they receive sweets in return, much like old English wassailers.
