Ambrosian Chant - History

History

The history of Milan as a center for religious music goes back to St. Ambrose. Ambrose is not known to have composed any of the Ambrosian chant repertory, much as Gregory the Great is not known to have composed any Gregorian chant. However, during his fourth-century tenure as Bishop of Milan, he is credited with introducing hymnody from the Eastern Church into the West. Ambrose composed original hymns as well, four of which still survive, along with music which may not have changed too much from the original melodies. In his writings, Ambrose refers only to the performance of antiphonal psalms, in which solo singing of psalm verses alternated with a congregational refrain called an antiphon.

Over time, the Milanese liturgy developed into the Ambrosian rite, which shares more in common with the Gallican and Mozarabic rites than with the Roman. Ambrosian chant developed to meet the particular needs of the Ambrosian liturgy. Although the Ambrosian rite is liturgically related to other rites and Ambrosian chant is musically related to other plainchant traditions, different categories of chant, different chant texts, and different musical styles make Ambrosian chant a distinct musical repertory. By the 8th century, this chant was attested to be normative across northern Italy, perhaps reaching into southern Italy as well.

Between the 8th and 13th centuries, however, the Carolingian chant commissioned by Charlemagne developed into what we now know as Gregorian chant, which began to influence and eventually replace most of the other Western plainchant traditions. By the 12th century, the Mozarabic, Gallican, Celtic, Old Roman, and Beneventan chant traditions had all been effectively superseded by Gregorian chant. Ambrosian chant alone survived, despite the efforts of several Popes over a period of several centuries to establish Gregorian hegemony. A chronicle by the Milanese historian Landolphus from around the year 1000 recounts a legend that two Sacramentaries, one Gregorian and one Ambrosian, were placed on an altar to see which chant had divine acceptance; miraculously, both books opened simultaneously, showing both were equally acceptable.

Ambrosian chant did not wholly escape Gregorian influence. The earliest 8th-century fragments, and the more complete chantbooks from the 11th and 12th centuries that preserve the first recorded musical notation, show marked differences between the Gregorian and Ambrosian repertories. Later additions to the Ambrosian repertory, whose style differs from the earlier chants, may reflect Gregorian influence. Although St. Charles Borromeo fought to keep the Ambrosian rite intact during Spanish occupation, a contemporary edition of Ambrosian chant, published by Perego in 1622, attempts to categorize the Ambrosian chants into the eight Gregorian modes, which is not generally accepted as an accurate reflection of the actual musical practice of the time.

Ambrosian chant has survived to the present day, although its use is now limited primarily to the greater part of the Archdiocese of Milan and environs, parts of Lombardy, and parts of the Swiss Diocese of Lugano. Most recently, it survived the changes to the liturgy established by Vatican II, in part due to the prior tenure of Pope Paul VI as Archbishop of Milan.
