Tejano (also called Tex‑Mex music) is a Mexican‑American popular style that blends the conjunto and norteño ensemble tradition with European dance rhythms (polka, schottische, waltz) and U.S. popular genres such as country, blues, funk, and rock. At its core are the accordion and bajo sexto, supported by electric bass and drum kit. Two main ensemble lineages coexist: the conjunto/accordion format and the orquesta Tejana format with saxophones and trumpets. Since the late 1970s, keyboards and synthesizers have been central to the "modern" Tejano sound, while cumbia, ballad, and two‑step grooves broaden its dance palette. Lyrics are typically in Spanish (often bilingual), centering on love, border life, working‑class pride, and festive social dance. The result is a dance‑forward, catchy, and distinctly borderlands music that feels at once Mexican in roots and American in production and stylistic openness.

Norteño (música norteña) is a Mexican regional style built around the bright timbre of the diatonic button accordion and the driving strum of the bajo sexto. Rooted in borderland dance music, it blends Central European polka, waltz, and schottische rhythms with Mexican corrido storytelling and ranchera songcraft. Characterized by brisk 2/4 polkas and lilting 3/4 waltzes, norteño songs range from narrative corridos about migration and everyday struggles to romantic ballads and party tunes. Traditional ensembles used tololoche (upright bass) and snare, while modern groups often add electric bass, full drum kits, and occasionally tenor sax (in the norteño-sax substyle) or tuba (in norteño-banda). The result is a dance-forward, story-rich music that bridges rural and urban audiences on both sides of the U.S.–Mexico border.

Polka is a lively Central European couple dance and musical style in a brisk 2/4 meter, characterized by its buoyant “oom‑pah” bass-chord accompaniment and bright, diatonic melodies. Originating in Bohemia (today’s Czech Republic) in the early 19th century, it quickly became a pan-European craze before taking root across immigrant communities in the Americas. Ensembles typically feature accordion or button box/concertina, clarinet or saxophone, trumpets/trombone, tuba or string bass, and drum kit, with regional variants highlighting different lead voices and rhythmic feels. While the classical ballroom tradition codified polka into formal strains (often AABB with a contrasting trio), folk and popular styles favor singable tunes, simple I–IV–V harmonies, and tempos commonly around 115–135 BPM, inviting upbeat social dancing and communal celebration.
