Regional Mexican ballad with slow sierreño guitar, soft requinto fills, brushed cajón pulse, and aching accordion swells; verse stays intimate and sparse, pre-chorus lifts with vocal harmony and rising guitar runs, chorus opens with stacked lead doubles and a chantable hook, bridge strips to lone guitar and breathy ad-libs before the final chorus returns fuller. Close-mic male vocals, emotional grit, delay throws on key lines, warm and wide mix.
