The formal dance traditionally performed during a quinceañera is called a vals.
Vals is the Spanish word for “waltz,” and the dance may be performed by the celebrant with family members, a partner, or the court of honor. In many celebrations, it is carefully rehearsed and presented as one of the reception’s central moments.
The dance tradition reflects the formal presentation and ballroom influence that became associated with elaborate quinceañeras. Contemporary families may choose pop songs, choreographed group numbers, or several styles instead of a conventional waltz.
A vals should not be confused with a single mandatory song. The music differs by country, generation, and family preference. The term identifies the waltz-style dance, while the wider program can include many additional performances.
