The customary name for the formal dance at a quinceañera reception is a waltz.
The waltz is often performed by the celebrant with members of her court of honor and sometimes with family members. It is usually rehearsed in advance and may be followed by a more modern choreographed dance or a general party.
The tradition reflects the formal presentation associated with the celebration. In many families, the dance is one of the most carefully planned parts of the event, alongside the entrance, photographs, meal, cake, and speeches.
Not every quinceañera uses a traditional waltz. Music and choreography vary widely by country, generation, and personal taste. A modern routine may incorporate pop, hip-hop, regional music, or several styles, but the formal waltz remains the conventional name for the ceremonial dance.
