Music

Music will enhance any ceremony. 

Try to select a soft meaningful track for entrances and as the background for actions during the ceremony such as signing a certificate.

You can really ramp up the energy by having something with a good beat for your exit.  This will get your guests into the party mood.

Always time your music and just play the right amount for entrances and exits.

Also make sure you listen to all the lyrics - there are lots of great songs but some of them are break-up songs !!
