opus [L], opera[pl], Op., Opp, WoO, Op. posth—work, as in a work of art. For unique identification, publishers/composers often assign an "opus number", abbreviated as "Op." (e.g. Op. 1). A range of works by opus number, uses the plural "opp." (e.g. "Opp. 1-3"). A single opus number may refer to a collection of works (e.g. a set of quartets) giving rise to designations like "Op. 1, No. 4". For misc. works without opus numbers, "WoO" is often used (e.g."Without Opus"). Posthumously assigned numbers may use "Op. posth". Opus numbers may not precisely reflect chronology (publication vs. composition), can be erroneous, sparse or duplicative. Thus, the works of some historically important composers may use separate catalog numbers (e.g. Bach, Haydn, Schubert). See wiki
string trio, Streichtrio [G], Trio d'archi [I], Trio à cordes [F], Trío de cuerdas [S]
—a work for three stringed instruments, most commonly violin, viola, and cello. A more rarefied form than the string quartet, perhaps because the texture is sparse (each instrument highly exposed) and the means are more difficult for natural harmonic richness. But these become challenges and assets in the great trios. Trios almost always emphasize countrapuntal writing with each of the three players in strong relief. Explore the string trio | wiki
trio (1)—an ensemble or work for 3 players
troppo [I], non troppo, trop [F]—too, too much. non troppo means "not too much". e.g. "Allegro ma non troppo" means fast, but not too much
