A "processional" refers to a ceremonial procession, often involving a group of people moving in an organized manner, typically for a special event or celebration. This can include religious ceremonies, graduations, or weddings, where participants walk together in a formal way, often accompanied by music. In many cultures, processions are significant rituals that symbolize unity and purpose. For example, in a wedding, the bride and groom may walk down the aisle as part of the processional, marking the beginning of the ceremony. Similarly, in a graduation, students may march in a processional to celebrate their achievements.
