The guitarrón, a large, six-string bass guitar fundamental to mariachi music, arose in 19th-century Mexico. While its exact origins are uncertain, it likely developed from or was influenced by European stringed instruments introduced by the Spanish. Characterized by its deep, resonant tone, the guitarrón boasts a distinctively arched back and a relatively short neck. Traditional construction employs various kinds of wood chosen for their tonal qualities and resilience. Although no single luthier is as prominently associated with the guitarrón's "modernization" as with the vihuela, its design evolved in tandem with mariachi music, becoming a cornerstone of its rhythmic and harmonic foundation.
