A waltz is the common English name for the formal dance traditionally performed by a quinceañera and her court.
The dance is often presented as part of the celebration’s formal program. The honoree and attendants may rehearse a choreographed routine, sometimes beginning with a slower traditional-style waltz before moving into other music.
Not every quinceañera includes a waltz, and modern celebrations may feature contemporary choreography, regional dances, or several musical styles. The waltz is a recognizable tradition rather than a mandatory requirement.
The term should not be confused with the entire reception. The waltz is one programmed performance within a broader event that may include a meal, speeches, symbolic presentations, and open dancing.
