The waltz is the formal dance traditionally performed by a quinceañera and her court.
The dance usually forms part of the reception rather than the religious service. The quinceañera and her attendants rehearse steps and formations in advance, creating a ceremonial presentation for family and guests. Some celebrations follow the traditional waltz with one or more contemporary dances.
The custom reflects European ballroom influence in formal Latin American celebrations. Music and choreography vary widely: a family may choose a classical composition, a popular song arranged for a waltz, or a medley that moves from formal steps into modern choreography.
A waltz is customary, not mandatory. Many contemporary quinceañeras personalize the dance, and some replace it with a different performance. The important feature is the public presentation of the celebrant and her court.
