Free-to-use (ie public domain or copyright-free) hymns and song means the words can be copied and sung to at least one tune with no concerns about copyright or performance licensing. Many such hymns are old/traditional - but where possible a variety of styles / genres are included.
Seasonal NoteMost communities have a familiar repertoire of public domain Christmas music, so at this time choosing free-to-use hymns is simple. The list below doesn't include all well known Christmas carols, just the ones that are a particularly good fit with the lectionary themes for this feast.
ReadingsFirst: Isaiah- The people that walked in darkness have seen a great light ... wonder councillor, mighty God, eternal father, prince of peace.
Psalm: Psalm 95 - Today a saviour has been born to us, he is Christ the Lord
Second: Titus - God's grace has been revealed and made salvation possible.
Gospel: Luke - Caesar called a census, so Joseph and Mary travelled to Nazareth. Mary gave birth in a manger because there was no room at the inn. Angels appeared to the shepherd, and told of the sign that they would find.
