Tejano music or Tex-Mex music (Texan-Mexican music) is the name given to various forms of folk and popular music originating among the Mexican-American populations of Central and Southern Texas. In recent years, artists such as Selena, often referred to as "The Queen of Tejano", La Mafia, Jay Perez, Mazz, and Jennifer Pena have transformed Tejano music from primarily a local, ethnic form of music to a genre with wide appeal in North America, Latin America, Europe, and beyond.

In the 1850s Europeans that came from Germany (first during Spanish time and 1830s), Poland and what is now the Czech Republic migrated to Texas and Mexico, bringing with them their style of music and dance. They brought with them the waltz, polkas and other popular forms of music and dance. However it was not until the Mexican Revolution (1910–1917) that forced many of these Europeans to flee Mexico and into South Texas, that their musical influence was to have a major impact on Tejanos.

Tejano music was born in Texas. Although it has influences from Mexico and other Latin American countries, the main influences are American. Contemporary classic Tejano artists such as Emilio and Raulito Navaira, David Lee Garza and Jay Perez exhibit influence from rock, blues, funk, and country. It is important to understand that Tejano music has various categories of music and bands. Three major categories are Conjunto, Orchestra and Modern. A Conjunto band is composed of accordion, bajo sexto, bass, and drum. Examples of Conjunto Bands are Esteban "Steve" Jordan, The Hometown Boys and Jaime de Anda y Los Chamacos. An Orchestra consists of bass, drum, electric guitar, synthesizer, and a brass section on which it relies heavily for its sound. It can also have an accordion in the band at times. An example of an Orchestra is Ruben Ramos and the Texas Revolution, The Liberty Band and The Latin Breed. A Modern Tejano band consists of synthesizers, drums, electric guitar, bass and at times an accordion. It relies heavily on the synthesizer for its sound. Modern bands are La Mafia, Selena and her band Selena Y Los Dinos, Shelly Lares, Jay Perez, and Jimmy Gonzalez Y Mazz. Other categories consist of Progressive, Pop and Urban Tejano music. All of these categories are classified as Tejano.
