Banda is a brass-based form of traditional Mexican music. Bandas play a wide variety of songs, including rancheras, corridos, cumbias, baladas, and boleros. Bandas are most widely known for their rancheras, but they also play modern Mexican pop, rock, and cumbias. Most Banda music is very clearly a dialect of polka and will seem familiar and appealing to fans of polka or traditional German and Polish music,anda music was established in the 1880s in the state of Sinaloa, Mexico, when it exploded into popularity in the 1890s throughout Mexico. Its roots come from the overlapping of Mexican music with German polka music. At the time, many German Mexicans lived in the states of Sinaloa, Chihuahua, Jalisco and Nuevo León. This greatly influenced northern Mexican music. Immigrants from northern Mexico brought the music to the United States. Initially popular in the southwest United States, primarily in Texas, California and Arizona, banda has followed the movement of Mexican immigrants to the Midwest United States and the rest of the country. Other notes on the origin of "banda" music resembling mid 20th century jazz: Mexicans who came in contact with Latin-based Jazz of Chicanos or Mexicans born and raised in the United States adopted jazz-like sounds in banda to further enrich the music type.
