The choir joins 60,000 singers from twenty-nine countries, which learn a shared music repertoire to allow participation in combined choir performances for liturgical and community events.  The singers, ages 9 to 18, perform locally, regionally, nationally and internationally.  Combined Choirs range in size from dozens to hundreds to thousands of singers.

   Pueri Cantores encourages high standards of performance and music selection.  It also promotes cultural understanding at home and abroad through travel and performance opportunities.
