"Una cosa più grande" is a collaboration born out of a strong friendship between Ermal Meta and Giuliano Sangiorgi. The song was written, composed, and arranged by both artists together, featuring their intertwined voices on an upbeat pop-rock melody. Giuliano Sangiorgi described the collaboration as having the "flavor of 'forever'" and a project he was eager to be part of.

It is a power ballad designed to be engaging, featuring a mix of electronic and melodic elements produced by Simone Bertolotti.

The song centers on the concept of and looking beyond oneself.

“Siamo amici, fratelli, amanti, genitori, figli” (We are friends, brothers, lovers, parents, children) “Almeno qui c'è lei” (At least here there is her/it)
