Contemporary Catholic liturgical music
Contemporary Catholic liturgical music encompasses a comprehensive variety of styles of music for Catholic liturgy that grew both before and after the reforms of the Second Vatican Council (Vatican II). The dominant style in English-speaking Canada and the United States began as Gregorian chant and folk hymns, superseded after the 1970s by a folk-based musical genre, generally acoustic and often slow in tempo, but that has evolved into a broad contemporary range of styles reflective of certain aspects of age, culture, and language.
