The recessional is when the bride and groom walk back down the aisle to leave the ceremony, followed by the immediate members of the the wedding party.
The couple should brief the organist, musicians or music co-ordinator on what music they would like played during the recessional.
There is generally an atmosphere of great happiness and relief; the celebrations are about to begin and the couple are officially Mr and Mrs.
The traditional order for the recessional is as follows:
bride and groom
chief bridesmaid and best man
mother of the bride and father of the groom
father of the bride and mother of the groom
the other bridesmaids, baby bridesmaids and pages
