The traditional ceremonial dance at a quinceañera is commonly called a vals.
Vals is the Spanish word for “waltz,” and the dance often forms part of the formal presentation at the reception. The celebrant may dance first with her father or another important family member, then with members of the court or other guests, depending on local custom.
Modern celebrations frequently add choreographed group routines, popular songs, or a second dance known as a surprise dance. These newer elements do not replace the traditional waltz everywhere, but they show how quinceañera customs adapt to contemporary music and family preferences.
The vals should not be confused with a particular musical song. Families can choose different waltz music, and some celebrations use a modern arrangement while retaining the name for the ceremonial dance.
