Rachmaninov, S.: Trio Elegiaque No. 2 / Shostakovich, D.: Piano Trio No. 2 (Compinsky Trio) (1945-1946)

The classical piano trio is a chamber-music genre written for three performers: piano, violin, and cello. It typically balances lyrical string writing with a harmonically and rhythmically active piano part, moving beyond “keyboard with accompaniment” into true conversational chamber texture. The core repertoire is rooted in European art music and is most closely associated with the Classical and Romantic eras, though composers continue to write piano trios in modern and contemporary idioms. Standard works are usually multi-movement (often 3–4 movements) and use forms such as sonata form, theme and variations, scherzo/minuet, and rondo, while later works may use cyclic form, extended techniques, or post-tonal harmony.
