Weding music applies to vocal and/or instrumental music performed at wedding rehearsals, rehearsal dinners, wedding ceremonies, and receptions (post-wedding party). In cultures of the Western Hemisphere, it initially provides background ambience for the audience as it assembles for the wedding. It then is used to announce and accompany a specific order of events, starting with the ritual seating of mothers and grandmothers by the ushers, followed by the entrance of the groomsmen and clergy, then the bridesmaids and lastly the bride and possibly the bridegroom self. All these events are accompanied by their own individual pieces, selected beforehand in conjunction with the musician(s) hired to perform. In lieu of live players, recorded music can be substituted to fulfill these functions.
