What are the rules around what music you can use for a Catholic ceremony? I've heard it needs to be sacred music, but I'm sure I've heard Canon in D used in a Catholic church before, so I'm kind of confused. I've also heard the bridal marches are not allowed in some churches. It's not a huge deal for me either way, but I would rather mix in some classical music if we can.
Also, I would love to hear what you used/ are using for ceremony music.
