Liturgical music

Liturgical music in the Christian West traces its roots to the Jewish synagogue and early Christian gatherings, where psalms and hymns were sung. By the medieval period, Gregorian chant, named after Pope Gregory I, became the standardized monophonic repertoire of the Roman Rite, codified in manuscripts such as the Graduale Romanum.¹ The development of polyphony in the Renaissance, exemplified by composers like Palestrina, marked a significant expansion, with the Council of Trent (1545–1563) affirming the importance of intelligible texts and the role of music in worship.²

The Protestant Reformation brought new liturgical music, with Martin Luther championing congregational chorales, while John Calvin favored metrical psalms. In the Catholic Church, the Baroque era saw the rise of the oratorio and the concerted mass, with composers such as Heinrich Schütz and Johann Sebastian Bach creating works that integrated music deeply into Lutheran liturgy.³ The Council of Trent's reforms also led to the codification of the Roman Missal, which influenced musical practice for centuries.

The Second Vatican Council (1962–1965) profoundly transformed Catholic liturgical music, allowing vernacular languages and encouraging active participation, leading to a proliferation of new hymns and folk-style masses.⁴ In Protestant traditions, the 20th century saw the rise of gospel music and contemporary worship songs, often accompanied by bands. The ecumenical Taizé community in France developed meditative, repetitive chants that have gained worldwide use.⁵ These developments reflect a broader trend toward inclusivity and cultural adaptation.

Beyond the mainstream, liturgical music includes the Byzantine chant of the Eastern Orthodox Church, which remains purely vocal and uses the Octoechos system of eight modes.⁶ The Ambrosian chant of Milan, named after Saint Ambrose, survives as a distinct rite with its own melodies. In the Ethiopian Orthodox Tewahedo Church, liturgical music employs the sistrum and drum, and the notation system is oral. The use of organ in Catholic liturgy was once controversial, with some early church fathers opposing instruments. Also, the Solesmes Abbey in France played a crucial role in the 19th-century restoration of Gregorian chant, influencing modern performance practice.⁷
