The number of songs to choose for your wedding ceremony can vary depending on several factors, such as the length of the ceremony, the specific moments you want to highlight, and your personal preferences. Here are some common songs and moments during a wedding ceremony:

Processional: This is when the wedding party enters the ceremony venue. You can choose a song for the parents, groomsmen, bridesmaids, and song for the entrance of the bride. The processional is generally 1-3 songs.

Interlude: If you have any special moments during the ceremony, such signing documents, unity candle lighting or a special reading, you may want to choose a song to accompany these moments.

Recessional: This is the grand exit of the newly married couple, and it's usually accompanied by an upbeat and celebratory song.

Generally, most wedding ceremonies include about 3-5 songs, but it ultimately depends on your preferences and the structure of your ceremony. You can choose additional songs for moments like the seating of the guests, during a slideshow or video presentation, or for any other significant part of the ceremony.

It's a good idea to work closely with your wedding DJ, planner, officiant, or musicians to determine the ideal number of songs for your specific ceremony. They can provide guidance and help you create a playlist that reflects your style and sets the desired mood for each moment.
