 Mariachi bands are small string bands whose music originated in Jalisco, Mexico. The bands typically contain a guitar, violins, a five-stringed Mexican guitar called a vihuela, a large bass guitar called a guitarrón, and a trumpet; all the musicians sing. Mariachi bands dress in charro costumes, the outfits of traditional Mexican horsemen.

Strangely enough, beluga whales appear to be great fans of mariachi music, as the video below shows.
