The traditional waltz performed at a quinceañera is called a vals.
Vals is the Spanish word for “waltz,” derived from the same European dance tradition as the English word. In a customary celebration, the quinceañera may perform a choreographed vals with her court, relatives, or other honored guests.
The dance is often one of the formal moments in the reception, alongside the entrance, the presentation of the celebrant, and other family rituals. Contemporary celebrations may add pop, Latin, or urban dance numbers after the vals.
Vals should not be confused with the entire quinceañera celebration: it names the waltz portion, not the party, Mass, or court. The exact choreography and participants vary by family, country, and community.
