Wedding bands are musical groups hired to provide live entertainment at wedding ceremonies and receptions. They may perform during drinks receptions, wedding breakfasts or evening celebrations, with line-ups ranging from small acoustic duos to larger groups with singers and instrumentalists. Their music can include pop, rock, soul, funk, jazz, swing, folk or other styles, depending on the band's repertoire. Services commonly include discussing the couple's preferred music, arranging a set list and providing sound equipment and lighting for the performance. Some bands can learn a particular song for a first dance, play background music between sets or supply recorded music during breaks. Bookings may cover one or more performances, and bands often agree timings and practical requirements with the couple or venue in advance. They may also perform at other events, but wedding bookings are tailored to the schedule and atmosphere of the day.
