Vals is the Spanish word for the formal dance often performed at a quinceañera.
The term comes from the Spanish word for waltz and names the ceremonial dance associated with the celebration. The vals may feature the quinceañera and her court, with participants moving in a prepared sequence before guests.
Historically, formal presentation dances helped display social grace and family support. In current celebrations, the vals can be traditional, heavily choreographed, or blended with modern music. Some families use the word for the formal opening dance even when the routine incorporates styles beyond a strict ballroom waltz.
Vals is not the same as baile, which is a broad Spanish word meaning dance or dancing. Nor is it a name for the entire quinceañera event. It identifies a particular ceremonial performance within a larger celebration that may include a religious service, speeches, dinner, and general dancing.
