Salvatore Moraccini is a Sardinian trombonist in the Orchestra Jazz della Sardegna (OJS), the Sassari big band founded in 1989 as the Blue Note Orchestra and renamed in 1996, one of the few Italian jazz orchestras that has operated continuously since its founding. A 2020 article in the Sardinian outlet Mediterranea Online, previewing a concert by his own Vilsait Jazz Band, describes Moraccini as OJS's co-founder and solo trombonist ("di cui Moraccini è cofondatore e trombone solista"); this is the only source found making the co-founder claim specifically for Moraccini, distinct from Gavino Mele's own documented role as the orchestra's founder and president, and it is reported here as a press characterization rather than independently verified against OJS's own institutional records. He remains on the orchestra's own published 2025-26 roster.

He is first individually confirmed on record in 2002, Discogs-credited on trombone for Giorgio Gaslini's Sacred Concert / Jazz Te Deum (Soul Note), a large-scale sacred jazz work recorded in a Sassari cathedral with OJS and the Coro Polifonico Santa Cecilia, featuring Paolo Fresu as trumpet soloist and Maria Pia De Vito among the credited voices.

His second Discogs-verified OJS recording is Il Brutto Anatroccolo (2005, Il Manifesto / Blu Studio), also directed and composed by Giorgio Gaslini, a big-band jazz setting of "The Ugly Duckling" first staged for the 1997 Time in Jazz festival; the trombone section on that recording also includes Emiliano Desole and Mauro Sanna. Separately, in 2005 Moraccini appears as a guest trombonist on Sardinian singer-songwriter Michele Pieraccini's In Volo (Ichnosound), a pop record outside the OJS context, alongside fellow OJS players Gianpiero Carta on saxophone and Raffaele Polcino on trumpet; this single outside session is Discogs-tagged Pop rather than Jazz and does not reflect his primary musical identity.

In August 2020 Moraccini formed the Vilsait Jazz Band with fellow OJS saxophonist Marco Maiore, a brass-and-percussion Dixieland sextet modeled on the historic New Orleans marching bands, playing 1920s-style repertoire. The group's documented lineup also includes trumpeter Emanuele Dau, OJS colleague Gianpiero Carta on clarinet, tuba player Giovanni Fenu and percussionist Bruno Brozzu; it performed in the "In Itinere 2020" concert series at the Accademia Bernardo De Muro in Tempio Pausania that August.

The Associazione Blue Note Orchestra's (ABNO) own official OJS discography page, not catalogued on Discogs, names Moraccini individually in the trombone section of two more recent recordings: Bruno Tommaso's Jazz Requiem Mass (2022) and La musica di Horace Silver (2025), the latter credited to the Blue Note Brass Sextet + Drums, a smaller OJS-affiliated ensemble distinct from his own Vilsait Jazz Band. Sardinian press and festival listings place that sextet, billed as the Blue Note Brass Sextet plus Drums, at civic and festival dates in Sassari and Stintino through 2025, performing tribute programs built around Horace Silver and Charles Mingus repertoire, and Moraccini also plays with the brass band of the Conservatorio "Luigi Canepa" in Sassari. OJS's own concert calendar lists further scheduled engagements for the orchestra into September 2026.

No birth date or birthplace for Moraccini is publicly documented on Discogs, Wikipedia in English or Italian, AllMusic, All About Jazz, or the Conservatorio "Luigi Canepa" faculty pages.

Moraccini's documented work spans two distinct registers. Inside the Orchestra Jazz della Sardegna he works in institutional big-band and orchestral jazz, including two Gaslini-directed recordings that fuse jazz with sacred choral and classical forms, and, more recently, small-ensemble tribute programs built around the hard-bop and soul-jazz repertoire of Horace Silver and the post-bop book of Charles Mingus. Outside the orchestra, he leads his own Vilsait Jazz Band toward an older vocabulary entirely, 1920s New Orleans-style Dixieland built on the historic marching-band tradition of the Mississippi delta. His single outside sideman credit, on a Sardinian pop singer-songwriter's 2005 album, is a guest date rather than a further stylistic strand of its own.
