One of these folk musical styles was the "son". This music featured string instruments. "Son" music divided into various regional varieties; the variety popular in the Jalisco area was called "son jalisciense", whose best known song, also referred to as "the mariachi national anthem", is "La Negra". Modern mariachi music developed from this "son" style, with "mariachi" as an alternative name for "son jalisciense". Early mariachi players did not look like those of today; they played only string instruments such as guitars and harps and dressed in typical peasant clothing: white pants and shirts with huarache sandals. Those who could play the "son jalisciense"/mariachi music could find work at "haciendas" at a higher rate than those who could not.
