A waltz is the European court dance commonly performed as the opening dance at a quinceañera.
The celebrant may first dance with her father or another honored partner, then join her court of honor in a choreographed waltz. This formal sequence is often called the vals, the Spanish word for waltz. It gives the reception a ceremonial opening and highlights the transition represented by the celebration.
The waltz tradition reflects the influence of European courtly and ballroom customs on Latin American elite society and later popular celebrations. In practice, many modern quinceañeras add contemporary music, themed choreography, or a surprise dance after the formal waltz.
A waltz is not required at every event. The exact music, partners, choreography, and order can differ substantially. The dance should also not be confused with tango, flamenco, or polka, which have different histories and movement traditions.
