 Carnevali worked for a time in the United States, in Chicago (conservatory or music college), New York City (Harvard-piano), and at St Patrick's Cathedral in New York City (where he probably succeeded Pietro Yon as organist).He spent some time in Algiers before returning to Rome.Some of his compositions include the four-part Mass settings Missa "Rosa Mystica", Missa "Stella Matutina", Missa "Ave Verum", Missa "Auxilium Christianorum", Missa "Jesu Salvator Mundi", and Missa "Mater Amabilis".
