As one of the leading operatic composers of his generation, Johann Simon Mayr nurtured a fascination with the chivalric stories of medieval England. Le due duchesse, an opera semiseria with buffa elements, is set during the reign of the 10th-century King Edgar. Huntsmen’s and Knights’ choruses and troubadour-like songs give great vivacity to a score that is both lyrical and dramatic. Mayr’s compound of Viennese Classicism and Italianate melodic beauty, allied to his ambitious writing and a skilful libretto, produced an important and influential opera couched in his own unmistakable idiom.
Sammartini had a long and active musical career, working as maestro di cappella or organist in as many as ten different churches, yet surprisingly few of his sacred compositions survive. In the sacred cantata Gerusalemme sconoscente ingrata, set to a text from another of his cantatas, La perfidia giudaica nella SS. Passione di Gesù Cristo, vocal texture is dominated by a typically Italianate melodiousness and virtuosity, while the orchestral writing is full of daring harmonies, sparkling themes, and an inexhaustible wealth of ideas.
