Polyphonic Music of the Renaissance

Polyphony — the combination of multiple independent vocal lines into a single, integrated composition — was the central musical technique of the Renaissance. From the late medieval era through the 16th century, composers developed increasingly sophisticated methods of combining voices, producing works of extraordinary complexity, beauty, and expressive power. The polyphonic tradition, which produced some of the greatest music in the Western canon, is the heart of Renaissance music, and it shaped the course of Western music for centuries to come.

What Is Polyphony?

Polyphony (from the Greek polus, “many,” and phonē, “sound”) is music in which two or more independent melodic lines are combined into a single composition. The lines can be sung or played by voices or instruments, and they interact according to a set of rules that govern the way they can move in relation to one another.

Polyphony is distinct from monophony, in which there’s a single melodic line, and from homophony, in which there’s a single melody supported by chords. In polyphonic music, each voice is an independent musical line, and the composer must manage the relationship between the lines with great care.

The technical rules of polyphony were developed over centuries of practice and theory. The most important included:

Counterpoint, the set of rules governing the relationship between two or more voices. The rules determine which intervals are allowed, how the voices should move in relation to one another, and how dissonances are to be resolved.
Voice leading, the art of moving each voice smoothly and expressively from one note to the next. Good voice leading requires attention to melodic shape, to the relationship between the voices, and to the overall flow of the music.
Imitation, the technique of having one voice repeat a melodic phrase that has been introduced by another voice. Imitation was a key feature of the Renaissance style, producing a sense of conversation among the voices.
Canon, the strictest form of imitation, in which one voice repeats exactly what another voice has sung, after a time delay. Canons, sometimes called “rounds,” were a particular specialty of the Renaissance.

The Origins of Polyphony

Polyphony has ancient roots. The ancient Greeks had a concept of polyphonic music, and there are references to polyphonic singing in the Old Testament. The tradition was preserved in the medieval church, where the singing of plainchant (single-line liturgical music) gradually developed into more elaborate forms.

The earliest examples of polyphony in the Western tradition are the organa of the 9th and 10th centuries, in which a plainchant melody was accompanied by a second voice moving in parallel motion. By the 12th century, polyphony had become more elaborate, with the development of the motet, a composition in which several different texts and melodies were combined.

The late medieval period saw an extraordinary flowering of polyphonic composition. The composers of the Ars Nova (New Art), including Guillaume de Machaut and Francesco Landini, produced works of remarkable complexity and beauty. The music of the late 14th century, with its syncopated rhythms and intricate counterpoint, was a high point of the medieval tradition.

The Renaissance Revolution

The Renaissance, beginning in the 15th century, transformed the polyphonic tradition. The new style, sometimes called the prima prattica (first practice) in contrast to the later Baroque seconda prattica (second practice), was characterized by:

Smooth, flowing vocal lines, with attention to the natural accentuation of the text.
Imitative counterpoint, in which a melodic phrase introduced in one voice is taken up by the others in turn.
Careful attention to the text, with the music reinforcing the meaning and the emotion of the words.
A sense of overall structure, with each section of a composition clearly delineated.
Balanced proportions, with the various parts of a composition related to one another in a harmonious way.

The new style was developed by the Franco-Flemish composers of the 15th century, who brought the technique to a high level of refinement. The most important of these composers was Josquin des Prez (c. 1450–1521), whose music embodied the new style and set the standard for the next generation of composers.

Josquin and the High Renaissance Style

Josquin des Prez, often called the greatest composer of the Renaissance, was the central figure in the development of the mature polyphonic style. Working in Italy and France, Josquin produced a body of work that combined technical mastery with emotional depth.

Josquin’s innovations included:

Imitative counterpoint, in which a melodic phrase introduced in one voice is taken up by the others in turn. The technique, which Josquin perfected, became a hallmark of the Renaissance style.
Word painting, in which the music illustrates the meaning of the text. Josquin’s settings of the words “descendit de coelis” (he descended from heaven) often feature descending melodic lines, and his treatments of the words “exaltavit” (he has exalted) often feature rising passages.
Motivic unity, in which a single melodic idea is used to organize an entire composition. Josquin’s masses and motets are often based on a single musical idea, transformed and developed in various ways.
Expressive intensity, in which the music conveys the emotion of the text. Josquin’s settings of the Passion, the Psalms, and other biblical texts are models of the integration of music and meaning.

Josquin’s music was admired across Europe. The poet Martin Luther, who was also a musician, said of Josquin: “He is the master of the notes, which must express what he wishes; other composers must do what the notes wish.” Josquin’s influence on subsequent generations of composers was enormous, and his style was the model for the polyphonic tradition of the 16th century.

Palestrina and the Roman School

Giovanni Pierluigi da Palestrina (c. 1525–1594) was the leading composer of the Roman school and the great master of the High Renaissance polyphonic style. Working in Rome, especially as the choirmaster of the Cappella Giulia at St. Peter’s Basilica, Palestrina produced an enormous body of sacred music, including 104 masses, more than 375 motets, and many other works.

Palestrina’s style, often called the Palestrina style, is characterized by:

Smooth, flowing vocal lines, with stepwise motion and careful attention to the text.
Imitative counterpoint, with each voice entering in turn with the same melodic material.
Clear tonal organization, with the voices moving in ways that make the underlying harmony clear.
Balance and proportion, with the various sections of a composition related to one another in a harmonious way.
Devotional expressiveness, with the music conveying the sacred text in a way that’s both elevated and intimate.

Palestrina’s most famous work, the Missa Papae Marcelli (Pope Marcellus Mass), became a model of sacred polyphony. According to a famous legend, the Mass was composed to demonstrate that polyphonic music could be intelligible and reverent, in response to a directive from the Council of Trent that the words of the Mass should be clearly heard. Whether or not the legend is true, the Mass has been admired for centuries for its serene beauty and its perfect balance.

The Venetian Polyphonic Style

The Venetian school of polyphonic composition, developed in the Basilica of St. Mark, had a distinctive character. The most important feature of the Venetian style was polychoral composition, in which two, three, or even four separate choirs, often placed in different parts of the church, sang in alternation.

The Venetian polychoral tradition was developed by Adrian Willaert (c. 1490–1562), the Flemish composer who served as maestro di cappella at St. Mark’s from 1527 until his death. Willaert, who had studied with Josquin, brought the imitative counterpoint of the Northern tradition to Venice, where it was combined with the Italian love of display and the spectacular architecture of St. Mark’s.

The polychoral tradition reached its peak with the Gabrieli family of composers. Andrea Gabrieli (c. 1533–1585) and his nephew Giovanni Gabrieli (c. 1554–1612) produced music for voices and instruments that exploited the spatial possibilities of St. Mark’s. The works of the Gabrielis, with their contrasting blocks of sound, their use of dynamic contrast, and their brilliant instrumental colors, are often seen as the bridge between the Renaissance and the Baroque.

The Madrigal and Secular Polyphony

The polyphonic tradition was not limited to sacred music. Secular polyphony, especially the madrigal, was an important part of the Renaissance musical landscape. The madrigal, a short vocal composition setting a poem for four to six voices, was the most characteristic secular form of the era.

The madrigal tradition developed in Italy in the early 16th century and quickly spread across Europe. The English madrigal school, which flourished in the late 16th and early 17th centuries, produced works of remarkable beauty and sophistication. Composers like Thomas Morley, Thomas Weelkes, and John Wilbye created a distinctive English style that combined Italian models with native English traditions.

The Decline of Polyphony

The polyphonic tradition, which had reached its peak in the works of Palestrina and the Gabrielis, began to give way to new styles in the early 17th century. The development of the basso continuo — a continuous bass line over which the upper parts could be freely composed — gave composers new flexibility. The rise of opera, with its emphasis on dramatic expression, called for a different kind of music. The seconda prattica (second practice), associated with the Baroque and with composers like Monteverdi, eventually replaced the prima prattica as the dominant style.

But the polyphonic tradition didn’t disappear. It continued to be cultivated in church music, especially in the Roman Catholic Church, where the tradition of Palestrina remained a model for sacred composition. In the 19th and 20th centuries, the polyphonic tradition was revived, and it remains an important part of the Western musical heritage.

The Legacy of Renaissance Polyphony

Renaissance polyphony is one of the great achievements of Western music. The works of Josquin, Palestrina, the Gabrielis, and their contemporaries are still performed and admired, and they have shaped the development of Western music in countless ways.

The polyphonic tradition, with its emphasis on the combination of independent voices, its technical sophistication, and its expressive depth, has been a model for composers from Bach and Handel to the present day. The techniques of counterpoint, voice leading, and imitation that were developed in the Renaissance remain the foundation of Western musical training.

An honest gap. The standard accounts of this period are, in many ways, the accounts of the literate, the urban, and the relatively well-off. The picture you get from the literature is necessarily a partial one, and any responsible overview has to flag the parts it is leaving out.
