chamber music, Kammermusik [G], musique de chambre [F], musica da camera [I], musica cameralis [L]—"Classical Music" for a small ensemble, generally 8 or fewer players with a canonical emphasis on 3-6 players. explore
fantasia, fantasy, fantazy, fantazia, phantasy, phantasie, fancy, fantasie [G], fantaisie [F] —generally, a piece of music favoring a free flight of expression over strict adherence to formal rules; suggesting an improvisational character. However, there are at least two more specific historical meanings: 1) the fantasia/fantasie/fancy of English Renaissance viol consort music and 2) Cobbett's Phantasie, an early 20th century form of single-movement chamber music inspired by the Renaissance fancy with the goal of stimulating new English chamber or "consort" music.
finale [I], final [F]—The final movement, sometimes explicitly titled thus
ma—but, however
moderato [I], moderamente, modéré [F], modérément [F]—moderately, at a moderate tempo, applying a touch of restraint to its related word(s), e.g. allegro moderato
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
scherzo—lively, brisk, typically in a triple meter; usually a three-part form with central, contrasting trio
string trio, Streichtrio [G], Trio d'archi [I], Trio de 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 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.
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
