El Comienzo begins with its first track "No Se Va", the first major success that Grupo Frontera had achieved during 2022. The song itself is a norteño cumbia. The norteño cumbia sound continues on the second track "Un x100to" with Puerto Rican singer Bad Bunny, which was a major hit single in 2023. The third track "En Altavoz", a collaboration with urban sierreño artist Junior H, is a ranchera with accordion, bajo quinto, tololoche, and alto horns. The last instrument is more common in the regional Mexican music of Sinaloa; very different from Grupo Frontera's northeastern Mexico-norteño style. On the fourth track "Cansado de Sufrir", Grupo Frontera returns to the sound of norteño cumbia. The fifth track "Las Flores" with the band Yahritza y su Esencia, is a grupero bolero. Grupo Frontera stated that it is their favorite song on the album.[13] The sixth track "De Lunes a Lunes" with the Colombian singer Manuel Turizo, is also a norteño cumbia. On the seventh track "Me Gustas", Grupo Frontera once again performs a ranchera with accordion, bajo quinto, tololoche, and alto horns. The eighth track "El Amor de Su Vida" features the band Grupo Firme, where they also return to the norteño cumbia genre. Grupo Frontera performs a country-style ballad with the ninth track on the album "Cuídala". They then return to a norteño cumbia on the tenth track "Que Vuelvas" with Carín León. Said song was released at the end of 2022 and achieved major success in 2023. The eleventh track "Le Va Doler" was released in May 2023 and is another norteño cumbia. The twelfth and final track "Ojitos Rojos" featuring the Argentine ensemble Ke Personajes, is a villera cumbia.
