comodo [I], commodo—comfortable, unhurried, easy
duo, duet, dueto [S], duetto [I], duett [G]—a work for two instruments; the ensemble itself
gavotte, gavotta—Originally a French folk dance that became a courtly dance with Louis XIV and subsequently used in Baroque suites. Moderate tempo in duple rhythm often beginning on an upbeat in a pick-up measure.
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
sostenuto [I], soutenu [F]—sustained, perhaps a bit slow
suite—a set of instrumental pieces (movements) played together to create a larger whole. Suites tend towards collections of dances, frequently in the same key, preceded by a prelude, introduction or overture.
