What musical style is a mariachi group, often hired for quinceañeras, associated with?

A mariachi group, often hired for quinceañeras, is associated with Mexican folk music.

Mariachi is a traditional Mexican ensemble and performance style recognized for instruments such as violins, trumpets, guitars, vihuelas, and guitarrones. Groups commonly perform songs about love, family, celebration, patriotism, and regional identity. Their appearance at a quinceañera can provide music for an entrance, a family serenade, or dancing during the reception.

Mariachi is not a single song or one fixed-size band. Instrumentation and group size vary, and professional ensembles may adapt their repertoire to the occasion. The musicians’ charro-inspired clothing is also strongly associated with mariachi performance.

Mariachi became internationally prominent during the twentieth century and was inscribed by UNESCO in 2011 on the Representative List of the Intangible Cultural Heritage of Humanity. It is specifically Mexican in origin, so it should not be categorized as Spanish flamenco or Caribbean reggae.
