Firmamento translates to "firmament" or "sky". It's a more poetic and grand word for the sky, evoking a sense of vastness and cosmic scale.
In "Big Bang," Amaral sings, "Cuando estalle el firmamento" (When the firmament explodes). This imagery connects to the song's title and theme, suggesting a powerful, universe-altering event that will reveal hidden truths and feelings. It's a striking word that adds a dramatic flair to the lyrics.
'Big Bang' spends its first verses turning down every role that would put her beneath someone else. 'Y no soy tu princesa' [And I'm not your princess], 'Ni quiero ser tu reina' [Nor do I want to be your queen], and 'Ni voy a ser tu geisha' [Nor will I be your geisha] reject three different fairy tales about pleasing a man, one right after another. What she asks for instead is plainer and harder to fake: 'Sólo quiero jugar' [I just want to play], someone to meet her as an equal instead of worshipping her from a pedestal.
The song locates the real power somewhere else: 'Está en la mente, mi amor' [Is in the mind, my love]. That line sets up the title's central image, because from here on the song talks about desire like it's a creation event. The hook, 'Justo en el comienzo del big bang' [Right at the beginning of the big bang], repeats four times in a row to close the song, so the chorus doesn't build toward that moment so much as sit inside it, echoing like the aftershock of the explosion itself.
Amaral is a Spanish pop-rock duo from Zaragoza, formed by singer Eva Amaral and guitarist Juan Aguirre. Their music often features strong melodies and Eva's powerful vocals.
They are well-known for popular songs like "Sin ti no soy nada" and "El universo sobre mí," which come from albums such as Estrella de mar and Pájaros en la cabeza. Their sound is generally upbeat and anthemic.
