The origin of mariachi can be traced back to the 1500s when Spanish explorers introduced stringed instruments and the concept of ensemble music to the indigenous culture of Mexico. Native and mestizo people adapted the instruments to their folk songs. From these early roots, mariachi dispersed and developed regional styles over many generations. The continuing influx of Europeans to Mexico brought in musical influences from opera, waltzes, polkas, and sentimental, piano-centric “salon music.” By the early 1900s, rustic, rural mariachi had migrated to Mexico City. There, the cowboy-musicians performed in plazas and restaurants wearing smart equestrian attire which became the template for the modern-day “charro” aesthetic. In post-revolutionary Mexico, national pride combined with advances in sound and film recording helped drive the popularity of mariachi throughout the country and across the border into North America.
