The formal choreographed dance at a quinceañera is commonly called a vals, the Spanish word for waltz.
The vals is often performed by the celebrant with members of the court of honor. In some celebrations, the event begins with a traditional waltz and later shifts into a more energetic contemporary routine. Families may select music from many genres, so the program is not limited to classical waltz music.
A vals is a dance segment, not the name of the entire quinceañera ceremony. It is also separate from the father-daughter dance, which some families include as another part of the celebration. Customs differ by country, region, and family, and many modern quinceañeras adapt the choreography or replace the formal dance with a personalized performance.
