Free Christmas music, choral arrangements

Looking for free music charts of traditional Advent music and carols?

If so, you might want to bookmark these sites:

ChoralWiki (CDPL.org) – Over 800 public domain carols & hymns (i.e. no licensing or royalty concerns) for Advent & Christmas.

ChristmasCarolMusic.org - Not as extensive as ChoralWiki, but helpful in that you can see at a glance what is offered (again, public domain)

Do you have site suggestions for free music?

Let me know!
