Classical trombone is the performance and repertoire of the trombone within the Western art‑music tradition, spanning solo works, concerti, chamber music (brass quintet and mixed ensembles), orchestral literature, and trombone choir pieces. Its sound world ranges from noble, chant‑like cantabile to brilliant, martial fanfares. Players read chiefly in bass and tenor clefs (with historical alto clef for alto trombone parts), exploit a broad dynamic range, and use a variety of mutes (straight, cup, harmon, plunger) for color. Idiomatic techniques include legato with natural slurs and lightly tongued connections, crisp staccato, lip slurs, agile articulation (double/triple tonguing), and carefully designed glissandi that respect the harmonic series. The genre encompasses historical sackbut repertoire adapted to modern instruments, Classical/Romantic orchestral roles, and a 20th–21st century expansion of solo literature and conservatory traditions worldwide.
