SofiaMari is a brand of diatonic button accordions distributed by Gulf Music Sales of Orange, California, aimed at players of conjunto, norteño, Tejano, and other regional Mexican and folk styles. The line is built around affordable, performance-ready instruments suited to beginners and intermediate players, with professional musicians also using them on stage.

The catalog centers on the SM-3412 and NSM-3412 — 34-button, 12-bass, three-switch diatonic accordions offered in the standard conjunto tunings of GCF (Sol), FBE (Fa), and EAD (Mi), as well as two-tone SMTT variants in tricolor finishes. Common features across the range include large pearl buttons, 19-fold bellows with diamond patterning, dual bellow straps with snaps, and a protective bellow pad. Most conjunto-oriented models ship without bass reeds, reflecting both space constraints and the playing conventions of the genre. The brand also offers cases, straps, and related accessories.

SofiaMari instruments are sold through Gulf Music Sales directly and through major retailers including Guitar Center, Musician's Friend, Music & Arts, Reverb, and Amazon. Gulf Music Sales also distributes the related Alacran accordion line, Coronado guitars, and SM Strings.
