A mariachi band consists of a minimum of 3 up to 9+ musicians. An authentic mariachi band will have hundreds of songs in their repertoire, and as well as performing traditional mariachi music, can include other Mexican and Latin style rhythms.

Mariachi music is a distinct type of traditional Mexican folk music that combines brass and string instruments. The music is accompanied by a distinctive singing style in its harmonies. It can feel rustic, aged, and inspiring in one moment, whimsical and comical in another.
