Summary

'''Antonio Cagnoni''' (8 February 1828 – 30 April 1896) was an Italian composer. Primarily known for his twenty operas, his work is characterized by his use of leitmotifs and moderately dissonant harmonies. In addition to writing music for the stage, he composed a modest amount of sacred music, most notably a ''Requiem'' in 1888. He also contributed the third movement, ''Quid sum miser'', to the ''Messa per Rossini'', a collaborative work created by thirteen composers to honor Gioacchino Rossini. ()
