시작

Gaho announced himself to most audiences through the Itaewon Class OST, and "시작" operates in a similar emotional register — the energy of a beginning, the slightly reckless courage of deciding to move toward something new. His voice is unusual in contemporary Korean pop: a tenor with genuine rock grit in its upper registers, capable of both delicate falsetto and full-throated power without the transition sounding mechanical. The production leans electric, with guitar-driven momentum that separates it from the acoustic introspection of most Korean ballads. There's urgency in the tempo, a sense that starting has its own physics — a momentum that, once engaged, becomes self-sustaining. The lyrics articulate the emotional choreography of beginnings: the way courage and fear are indistinguishable at the moment of departure, how the commitment to start transforms everything that follows. Culturally, Gaho's music connects to a generation of Korean listeners who came of age during intense personal and social reinvention — his themes of self-determination resonate with particular force for that audience. The song builds to a final third that becomes almost anthemic, his voice and production both expanding to fill the emotional space the lyrics have been constructing. It's music for the first day of something, for the moment after a decision when action finally replaces deliberation and the weight of waiting is suddenly, gratefully, gone.
