Announcing the first dance at a wedding is a way to get the party started and set the tone for the night. There are a few different ways to make the announcement, and it generally depends on the formality of the event. For a more formal affair, the MC or DJ can make an announcement over the microphone, letting everyone know that it's time for the first dance. For a less formal wedding, the first dance can be announced simply by turning up the music and getting everyone out on the dance floor. In this case, there's no need for any formalities - just cue up the first song and let everyone know it's time to start dancing! No matter how you announce it, the first dance is always a special moment at a wedding.
