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.
