Stefano Travaglini was an Italian double bassist who spent more than four decades as one of the working rhythm-section players of the Adriatic coast jazz scene, based out of Riccione in Emilia-Romagna. He was born in Italy's Marche region and settled in Riccione, which he made his adopted home for the rest of his life. He graduated in 1980 with a diploma in double bass from the Conservatorio "Gioachino Rossini" in Pesaro, and began his professional jazz career two years later, in 1982, joining tenor saxophonist Giorgio Baiocco's quartet.

Travaglini's working life was built almost entirely as a sideman and ensemble member rather than as a leader. He was a member of trumpeter Marco Tamburini's quintet, the Capolinea Big Band directed by tenor saxophonist Gianni Basso, Guido Manusardi's trio, the progressive/jazz-rock-descended group Area 2, and bassist Massimo Pasi's quintet, and Discogs independently lists him as a member of Idra, a short-lived Italian jazz "supergroup" active in the late 1980s alongside pianist Paolo Birro, saxophonist Renato D'Aiello, keyboardist Patrizio Fariselli (of the prog-rock group Area) and bassist Roberto Monti, though no individual release under the Idra name appears in his own documented discography. In 1988 he won first place at the Coppa del Jazz with Marco Tamburini's ensemble; the surviving Discogs-indexed record of this period, the various-artists compilation "Jazz Contest '88," credits Travaglini on bass alongside Tamburini on trumpet and Roberto Rossi on trombone for the track "Eduard." In 1990 he toured Italy with American guitarist Joe Diorio, and in 1993 he taught and performed at advanced jazz courses in Tirano.

Obituaries published after his death describe him as having performed over his career alongside Franco Cerri, Maurizio Giammarco, Paolo Fresu, Fabrizio Bosso, Lee Konitz and Peter Erskine; these are bio-only claims from press coverage, not independently confirmed by a specific Discogs release credit under Travaglini's own name, so they are reported here with that caveat rather than treated as verified connections. What is independently Discogs-verified is a narrower but genuine body of session work: alongside the Tamburini-led "Jazz Contest '88" date above, Travaglini is credited on bass on the Marco Volpe Band's "Exacting Work" (1990, Splasc(h) Records), with pianist Danilo Rea; on Guido Guidoboni's "Xoanon" (1988, Splasc(h) Records); on "Live At Down Town" (1996, Splasc(h) Records), a quartet session billed to Gianni Basso and the Guido Manusardi Trio that also features drummer Massimo Manzi; and on a handful of other Splasc(h)-label sideman dates into the 2000s and 2010s. He also co-billed an album under his own name, "Ariminor Blues" (1992, Splasc(h) Records, with guitarist Roberto Monti).

Travaglini remained professionally active into his final year. In 2024 he recorded double bass on "Urban Jungle," an independently released album led by Stefano Paolini featuring Roberto Rossi, Simone La Maida and Emilio Marinelli, and in his last working period he performed with singer Martina Grossi's quartet and took part in "L'Evasione di Chet," a 2024 theatrical production centered on the life of Chet Baker. He died in Riccione on March 12, 2025, at the age of 69; the Riccione municipal administration described him publicly as "a refined musician." His funeral was held at the Chiesa Mater Admirabilis in Riccione on March 14, 2025.

A name-collision note: Discogs separately lists a second, unrelated artist also named Stefano Travaglini (Discogs artist ID 7911340), an Italian pianist and composer associated with the label Notami Jazz, the website stefanotravaglini.com, and album titles including "Ellipse" (2017) and "The Long Line" (2018/2019, a piano-duo recording with pianist Massimiliano Coclite). That release, "The Long Line," is misfiled on Discogs under the bassist's artist ID (5337057) even though press coverage and the pianist's own website confirm it as a two-piano recording by the other, still-active Stefano Travaglini; it has been excluded from this profile and from the discography in this folder for that reason. The two men are not related as documented, and this profile concerns only the double bassist who died in March 2025.

Travaglini's work sits in the mainstream, bebop-rooted combo and big-band tradition that has defined much of the Adriatic coast's regional jazz scene since the 1980s. His documented recordings are standards-and-originals quartet/quintet sessions on the Splasc(h) Records label, Bologna's principal Italian jazz imprint of the period, built around the same working-musician circuit of Marche and Romagna-based players who moved between each other's working groups and festival dates rather than a single fixed band. His membership in Gianni Basso's Capolinea Big Band and in the short-lived Idra "supergroup" alongside a former member of the progressive-rock group Area reflects a career spent inside ensemble jazz, as a section and rhythm-section player first, rather than one built around a personal leader discography.
