"L'essenziale" was commercially successful in Italy, debuting at number one on the FIMI Singles Chart and being certified quadruple platinum for domestic downloads exceeding 120,000.[5] In an interview released to the Italian magazine TV Sorrisi e Canzoni, Mengoni described "L'essenziale" as "an Italian-style ballad in the tipping point between love and social issues".[6] He later explained that the song refers to all kind of relations, and that it is "about the necessity to go back to essentiality, to open to new emotions and to overcome the difficulties of these days", with the expression of "the urgency to free people from the superstructures and the general crisis".[14] On 6 April of that year, Mengoni performed the song during the first episode of the talent show Amici di Maria De Filippi, for a duet with contestant Verdiana Zangaro.[21] On 21 February of that year, the single was certified gold by the Federazione Industria Musicale Italiana,[22] while it went multi-platinum by 2 April 2013, denoting domestic downloads exceeding 60,000 units.[24] "L'essenziale" later became the best selling-single in Italy during the first six months of 2013 and the third best-selling single of the year, behind "Get Lucky" by Daft Punk and Pharrell Williams, and Avicii's "Wake Me Up".On the first night of the contest, "L'essenziale" won against the latter as the song to be performed by Mengoni for the next stages of the competition, receiving a score of 52.17% based on televotes combined with preferences of a jury composed of music journalists.[38] On the final night of the song contest, held on 16 February 2013, "L'essenziale" finished in first place, receiving 36% of votes in the last round of the competition, beating the remaining entries within the top three: Elio e le Storie Tese's "La canzone mononota" and Modà's "Se si potesse non morire".[46] While singing the song, he was alone on stage, performing with modest movements and colours,[47] and wearing a suit designed for him by Salvatore Ferragamo's Massimiliano Giornetti.
