Polyphony

Historical context

European polyphony rose out of melismatic organum, the earliest harmonization of the chant. During the 12th century, composers such as Léonin and Pérotin developed the organum that had been introduced centuries earlier, and also added a third and fourth voice to the now homophonic chant. In the 13th century, the chant-based tenor was becoming altered, fragmented, and hidden beneath secular tunes, obscuring the sacred texts as composers continued to develop polyphonic techniques. The lyrics of love poems might be sung above sacred texts in the form of a trope, or the sacred text might be placed within a familiar secular melody. The oldest surviving piece of six-part music is the English rota Sumer is icumen in (c. 1240).^[10]

Western Europe and Roman Catholicism

European polyphony rose prior to, and during the period of the Western Schism. Avignon, the seat of popes and then antipopes, was a vigorous center of secular music-making, much of which influenced sacred polyphony.^[11]

The notion of secular and sacred music merging in the papal court also offended some medieval ears. It gave church music more of a jocular performance quality supplanting the solemnity of worship they were accustomed to. The use of and attitude toward polyphony varied widely in the Avignon court from the beginning to the end of its religious importance in the fourteenth century.

Harmony was considered frivolous, impious, lascivious, and an obstruction to the audibility of the words. Instruments, as well as certain modes, were actually forbidden in the church because of their association with secular music and pagan rites. After banishing polyphony from the Liturgy in 1322, Pope John XXII warned against the unbecoming elements of this musical innovation in his 1324 bull Docta Sanctorum Patrum.^[12] In contrast Pope Clement VI indulged in it.

The oldest extant polyphonic setting of the mass attributable to one composer is Guillaume de Machaut's Messe de Nostre Dame, dated to 1364, during the pontificate of Pope Urban V. The Second Vatican Council said Gregorian chant should be the focus of liturgical services, without excluding other forms of sacred music, including polyphony.^[13]

Protestant Britain and the United States

English Protestant west gallery music included polyphonic multi-melodic harmony, including fuguing tunes, by the mid-18th century. This tradition passed with emigrants to North America, where it was proliferated in tunebooks, including shape-note books like The Southern Harmony and The Sacred Harp. While this style of singing has largely disappeared from British and North American sacred music, it survived in the rural Southern United States, until it again began to grow a following throughout the United States and even in places such as the United Kingdom, Germany, Poland, and Australia, among others.^{[15][16][17][18]}

Balkan region

Polyphonic singing is traditional folk singing of this part of southern Europe. It is also called ancient, archaic or old-style singing.^[19][20]

• Byzantine chant
• Ojkanje singing, in Croatia, Serbia and Bosnia and Herzegovina
• Ganga singing, in Croatia, Montenegro and Bosnia and Herzegovina
• Bosnian root music in the Podrinje region of Bosnia and Herzegovina
• Epirote singing, in northern Greece and southern Albania (see below)
• Iso-polyphony, in southern Albania (see below)
• Gusle singing, in Serbia, Montenegro, Bosnia and Herzegovina, Croatia and Albania
• Izvika singing, in Serbia
• Dvuglas singing in Southern Bulgaria: woman choirs in Shopluk (Bistritsa Babi) and in Rhodopes (Nedelino), as well as men choirs in Bansko, Pirin Macedonia^[21]

Incipient polyphony (previously primitive polyphony) includes antiphony and call and response, drones, and parallel intervals.

Balkan drone music is described as polyphonic due to Balkan musicians using a literal translation of the Greek polyphōnos ('many voices'). In terms of Western classical music, it is not strictly polyphonic, due to the drone parts having no melodic role, and can better be described as multipart.^[22]

The polyphonic singing tradition of Epirus is a form of traditional folk polyphony practiced among Aromanians, Albanians, Greeks, and ethnic Macedonians in southern Albania and northwestern Greece.^[23][24] This type of folk vocal tradition is also found in North Macedonia and Bulgaria.

Albanian polyphonic singing can be divided into two major stylistic groups as performed by the Tosks and Labs of southern Albania. The drone is performed in two ways: among the Tosks, it is always continuous and sung on the syllable 'e', using staggered breathing; while among the Labs, the drone is sometimes sung as a rhythmic tone, performed to the text of the song. It can be differentiated between two-, three- and four-voice polyphony.

In Aromanian music, polyphony is common, and polyphonic music follows a set of common rules.^[25]

The phenomenon of Albanian folk iso-polyphony (Albanian iso-polyphony) has been proclaimed by UNESCO a "Masterpiece of the Oral and Intangible Heritage of Humanity". The term iso refers to the drone, which accompanies the iso-polyphonic singing and is related to the ison of Byzantine church music, where the drone group accompanies the song.^[26][27]

Corsica

The French island of Corsica has a unique style of music called Paghjella that is known for its polyphony. Traditionally, Paghjella contains a staggered entrance and continues with the three singers carrying independent melodies. This music tends to contain much melisma and is sung in a nasal temperament. Additionally, many paghjella songs contain a picardy third. After paghjella's revival in the 1970s, it mutated. In the 1980s it had moved away from some of its more traditional features as it became much more heavily produced and tailored towards western tastes. There were now four singers, significantly less melisma, it was much more structured, and it exemplified more homophony. To the people of Corsica, the polyphony of paghjella represented freedom; it had been a source of cultural pride in Corsica and many felt that this movement away from the polyphonic style meant a movement away from paghjella's cultural ties. This resulted in a transition in the 1990s. Paghjella again had a strong polyphonic style and a less structured meter.^[28][29]

Sardinia

Cantu a tenore is a traditional style of polyphonic singing in Sardinia.

Georgia

Polyphony in the Republic of Georgia is arguably the oldest polyphony in the Christian world. Georgian polyphony is traditionally sung in three parts with strong dissonances, parallel fifths, and a unique tuning system based on perfect fifths.^[30] Georgian polyphonic singing has been proclaimed by UNESCO an Intangible Cultural Heritage of Humanity. Popular singing has a highly valued place in Georgian culture. There are three types of polyphony in Georgia: complex polyphony, which is common in Svaneti; polyphonic dialogue over a bass background, prevalent in the Kakheti region in Eastern Georgia; and contrasted polyphony with three partially improvised sung parts, characteristic of western Georgia. The Chakrulo song, which is sung at ceremonies and festivals and belongs to the first category, is distinguished by its use of metaphor and its yodel, the krimanchuli and a "cockerel’s crow", performed by a male falsetto singer. Some of these songs are linked to the cult of the grapevine and many date back to the eighth century. The songs traditionally pervaded all areas of everyday life, ranging from work in the fields (the Naduri, which incorporates the sounds of physical effort into the music) to songs to curing of illnesses and to Christmas Carols (Alilo). Byzantine liturgical hymns also incorporated the Georgian polyphonic tradition to such an extent that they became a significant expression of it.^[31]

Chechens and Ingushes

Chechen and Ingush traditional music can be defined by their tradition of vocal polyphony. Chechen and Ingush polyphony is based on a drone and is mostly three-part, unlike most other north Caucasian traditions' two-part polyphony. The middle part carries the main melody accompanied by a double drone, holding the interval of a fifth around the melody. Intervals and chords are often dissonances (sevenths, seconds, fourths), and traditional Chechen and Ingush songs use sharper dissonances than other North Caucasian traditions. The specific cadence of a final, dissonant three-part chord, consisting of fourth and the second on top (c-f-g), is almost unique. (Only in western Georgia do a few songs finish on the same dissonant c-f-g chord.)^{[7]: 60–61}
