Music you may require for a ceremony is a Procession song for the bride, a song of two for the Signing of the Register as well as a Recessional song (when you are presented to your guests as husband and wife).

Usually you have music being played for 15 minutes before the ceremony as well as after the ceremony to keep the guests entertained while they wait for your big entrance!

Style of music will also depend on the location too, as some churchs / priests prefer classical music only.

One essential thing to consider for a outdoor ceremony if you are not using live music is the supply of power. Sometimes a battery powered speaker may be necessary for your needs.
