A waltz is traditionally performed at the formal opening of a quinceañera reception.
The quinceañera often begins a choreographed waltz with her court or with a parent. The dance gives the reception a formal presentation and lets the celebrant be introduced to guests in a highly visible way. In Spanish-speaking communities, the dance may be called the vals.
The custom reflects older European courtly and ballroom traditions that became part of elite and middle-class celebrations in Latin America. Over time, families incorporated the waltz into a distinctly Latin American coming-of-age event. The routine may be elegant and traditional, or it may be followed by a contemporary surprise dance.
A waltz is not the only music used at a quinceañera. Many modern celebrations include cumbia, salsa, merengue, regional Mexican music, pop, and hip-hop. The traditional waltz remains recognizable because it marks the formal presentation, even when the rest of the program is highly modern.
