Church music
Music for the Catholic Church includes instrumental music such as “church cantatas”.  Arcangelo Corelli and Wolfgang Amadeus Mozart wrote many examples of these.  Mozart also wrote several masses.  Great Italian composers of the 16th and 17th centuries who wrote church music include Giovanni Gabrieli and  Claudio Monteverdi.  In the 19th century Rheinberger and  Max Reger wrote music in the Romantic style.  French composers of this time wrote in a style which was similar to secular music.
