Johann Simon Mayr’s music stands on the cusp between the Classical and Romantic eras. The expressive lyrical qualities in his religious music reflects a career in which he composed nearly 70 operas. The Messa solenne follows the Italian tradition of messa concertata and contains the full ordinary – a rarity for Mayr’s output in this genre. The work’s polyphonic sections made an especially lasting impression on churchgoers of the time, as witnessed by Mayr’s first biographer, Girolamo Calvi, who wrote enthusiastically about this work’s ‘exquisite vocal writing’ and ‘profoundly thrilling’ virtuosity – qualities that have remained hidden for nearly 200 years.

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.

Mayr's Telemaco was a product of turbulent political times in the Republic of Venice, which had been occupied by Napoleon's troops in late 1796. Military elements, with incorporated marches, feature strongly in a score that brought to contemporary Venetian theatre many of the innovative elements that were in vogue on the operatic stages of Paris. Taking classical Greek mythological material, Mayr fashioned an opera full of colour, interweaving instrumental interludes and dances into his arias, cavatinas and choruses, and crafting his own very personal vision of the nwe Italian opera seria.

"Mayr's Masses were in demand across Europe, and their composition is rooted in the Italian tradition of the messa concertata which demands division into separate vocal numbers. The Mass in E minor has long been recognised as an outstanding example of Mayr's late style, with its polyphonic mastery and dialogues between singers and concertante solo instruments being exceptionally convincing. The Mass in F minor evokes both joy and deep melancholy, though accompanied, as always, by Mayr's notable gift for melodic beauty."
