Tololoche is a strand of Regional Mexican music distinguished by its use of the tololoche—an acoustic, gut/nylon‑strung upright bass smaller than the orchestral contrabass—played with pronounced, percussive slap and walking lines. Typically heard in early norteño/campirano trios and quartets, the ensemble pairs accordion and bajo sexto with the tololoche, and sometimes a light snare (tarola). Repertoires center on polkas (2/4), waltzes (3/4), rancheras, and corridos, with brisk dance tempos and narrative lyrics about rural life, romance, travel, and bravado. The sound is earthy, resonant, and highly rhythmic: the tololoche’s slap articulations supply the backbeat while its walking bass outlines harmony, giving the music its unmistakable bounce.

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.

Corrido is a Mexican narrative ballad tradition that tells real or imagined stories about heroes, outlaws, battles, tragedies, and contemporary events. It is strophic, usually built from octosyllabic lines organized into quatrains with assonant rhyme, and features a declamatory vocal delivery designed to make the storyline clear. Musically, corridos are commonly set to dance-derived rhythms such as polka in 2/4 or waltz in 3/4, reflecting 19th‑century European influences absorbed in northern Mexico. They are performed by different ensembles—most famously norteño groups with accordion and bajo sexto, mariachi with violins and trumpets, or banda with brass and tuba—yet the poetic form and storytelling remain central. Typical corridos open with a saludo (greeting/announcement), present the narrative in chronological episodes rich with names, places, and dates, and close with a despedida (farewell or moral). Modern variants include narcocorridos and, more recently, corridos tumbados that fuse the narrative form with contemporary urban and trap aesthetics.
