The album is composed of thirteen tracks, eleven of which were written by the singer herself,[5] with the authorial participation of Elisa Toffoli, Federica Abbate, Joan Thiele, Alessandro Mahmood, Davide Petrella, and production by Francesco "Katoo" Cattiti, Dardust, Drillionaire, ITACA and Zef.

[6] In an interview for Vanity Fair Italia, Elodie explained the process of producing and writing the songs on the album:[7]"I had the immense opportunity to be able to collaborate with a group of artists with whom I have an important relationship, from Dardust to Mahmood to Federica Abbate, Elisa, Davide Petrella, all people who have built my path.

"Claudio Cabona of Rockol described the project as "the sharpest snapshot of today's Elodie," thanks to "quality pop and dance songs" that "were able to tell the story of the singer's transformation."

"[10] Marco Macchi of Newsic.it appreciated Elodie's musical evolution undertaken within OK. Respira, highlighting how the record turns out to be "contemporary electro-pop" thanks to the work done by the production team, citing Dardust of all people, concluding that the singer has become "the perfect Italian dancefloor star, between Madonna and Kylie Minogue.

"[7] Gabriele Fazio of Agenzia Giornalistica Italia claimed that the album represents one of " the most authentic pop manifestations possibly in the entire history of Italian music," finding, however, that it elicited a "deadly boredom" from the listener because the songs "do not pretend to communicate anything, but only to function on a sonic level.
