Mariachi is a traditional Mexican music and a fundamental element of Mexican culture. Traditional Mariachi groups, made up of two or more members, wear regional costumes adapted from the charro costume and interpret a broad repertoire of songs on stringed instruments.

Mariachi music as we know it today originated in the Mexican state of Jalisco, according to popular legend in the town of Cocula, in the 19th century. The mariachi was the distinctive version of the Spanish theatrical orchestra of violins, harp and guitars which developed in and around Jalisco.
