Padre José Maurício Nunes Garcia (1767-1830) was perhaps the most prolific, revered, and successful composer in 18th and 19th century colonial and postcolonial Brazil. Padre José Maurício's favor with King Dom João VI, the Portuguese Royal Court, and a catalogue of hundreds of compositions, is validation of his success, yet there is comparatively little academic research and recognition in comparison to his European contemporaries. Padre José Maurício's employment of the trombone within his ambitious capstone, his Missa de Santa Cecília showcases his recognizable and original compositional language. The influence of two contemporaries of Padre José Maurício, Wolfgang Amadeus Mozart (1756-1791) and Gioachino Rossini (1792-1868), had an integral and clear influence on the Missa de Santa Cecília without resulting in rote imitation. Mozartian text emphasis, independent part writing, technical demand, and traditional use of the trombone for sacred or supernatural imagery were synthesized by Padre José Maurício swiftly and originally. Simultaneously, Rossinian orchestration, close scoring, limited range, subverted structural arrivals, and emulated percussive effects were personalized and employed by Padre José Maurício. His insular development and instantaneous adaptation of new orchestration and theatrical models yields trombone writing that is idiomatic, in alignment with sacred and symphonic tradition, and essential to the study of the trombone in the early 18th century. Padre José Maurício's trombone writing is significant for primarily two reasons: it is at odds with current historical trombone texts, and his insular development in a hegemonic society yielded an individual compositional style
