Monophonic plainchant served as the basis for early polyphonic experiments
Chant melodies provided the cantus firmus (fixed melody) for polyphonic compositions
Gregorian repertoire influenced the modal and melodic characteristics of early polyphonic works
Liturgical calendar and texts shaped the development of polyphonic forms
Emergence of organum
Organum marked the first systematic approach to combining multiple melodic lines
Initially involved adding a parallel voice to the existing chant melody
Evolved from simple parallel motion to more complex relationships between voices
Treatise "Musica Enchiriadis" (c. 900) provided early theoretical descriptions of organum techniques
Organum practice spread from monasteries to cathedral schools, fostering regional stylistic variations
Early polyphonic forms developed gradually from the 9th to 12th centuries
Represented experimental stages in combining multiple voices within a musical composition
Laid the foundation for more complex polyphonic structures in later medieval and Renaissance music
Parallel organum
Earliest form of organum, featuring strict parallel motion between voices
Voices moved in perfect fourths, fifths, or octaves above or below the original chant melody
Created a harmonically consonant but rhythmically rigid texture
Primarily used in liturgical settings to enhance the solemnity of chant performance
Gradually evolved to include occasional deviations from strict parallelism
Free organum
Allowed for greater independence between voices compared to parallel organum
Introduced contrary and oblique motion alongside parallel movement
Voices could move at different speeds, creating a more dynamic musical texture
Often featured a faster-moving upper voice against a slower-moving lower voice (tenor)
Expanded the harmonic possibilities and expressive range of polyphonic composition
Melismatic organum
Characterized by highly ornate upper voices set against a sustained lower voice
Lower voice typically held long notes derived from the original chant melody
Upper voice(s) featured extensive melismatic passages (multiple notes sung to a single syllable)
Created a more florid and elaborate musical texture
Exemplified in the Magnus Liber Organi from the Notre Dame school
Notre Dame school
Refers to the group of composers and theorists associated with the Notre Dame Cathedral in Paris
Flourished during the late 12th and early 13th centuries
Played a crucial role in the development of polyphonic composition and notation
Innovations from this school influenced sacred music throughout Europe
Léonin and Pérotin
Léonin (fl. 1150s-1201) considered the first major composer of the Notre Dame school
Compiled the Magnus Liber Organi, a collection of two-voice organum settings for the liturgical year
Pérotin (fl. c. 1200) expanded on Léonin's work, creating more complex three- and four-voice compositions
Pérotin's innovations included the use of rhythmic modes and the development of the motet form
Both composers significantly advanced the techniques of discant and melismatic organum
Development of discant style
Discant style featured note-against-note counterpoint in the upper voices
Contrasted with the more florid, melismatic style of earlier organum
Employed rhythmic modes to organize the musical pulse and create rhythmic patterns
Allowed for greater textual clarity in polyphonic settings
Influenced the development of the motet and other polyphonic genres
Ars antiqua period
Refers to the period of musical style and theory from c. 1170 to 1310
Characterized by the codification of rhythmic notation and the emergence of new polyphonic forms
Centered primarily in France but influenced musical practices throughout Western Europe
Laid the groundwork for the more complex styles of the subsequent Ars nova period
Conductus vs motet
Conductus
Non-liturgical Latin song for one or more voices
All voices typically moved together syllabically
Often used as processional music or to introduce other pieces
Texts were newly composed, not based on pre-existing chant
Motet
Polyphonic composition with different texts in each voice
Usually based on a pre-existing chant melody in the lowest voice (tenor)
Upper voices featured more rapid movement and independent texts
Evolved into both sacred and secular forms
Rhythmic innovations
Introduction of rhythmic modes systematized the organization of musical time
Six rhythmic modes based on poetic meters provided a framework for notating rhythm
Development of ligatures to represent groups of notes within a single rhythmic unit
Emergence of ternary division of time, influenced by the concept of perfection in medieval theology
These innovations allowed for more precise notation and performance of complex rhythmic structures
Notational advancements
Notational developments during this period were crucial for the evolution of polyphonic music
Enabled more accurate preservation and transmission of complex musical ideas
Facilitated the composition and performance of increasingly sophisticated polyphonic works
Modal notation
System of rhythmic notation developed in the late 12th century
Based on six rhythmic modes derived from poetic meters (trochaic, iambic, dactylic, etc.)
Used specific note shapes and ligatures to indicate rhythmic patterns
Allowed for the notation of more complex rhythmic relationships between voices
Limited in its ability to represent irregular rhythms or mixed meter
Mensural notation
Evolved from modal notation in the late 13th century
Introduced individual note shapes to indicate specific durations (longa, brevis, semibrevis)
Allowed for both binary and ternary divisions of rhythmic units
Enabled more precise and flexible notation of rhythm and meter
Formed the basis for the development of white mensural notation in the Renaissance
Compositional techniques
Early polyphonic composers developed various techniques to create coherent multi-voiced works
These techniques laid the foundation for more complex contrapuntal practices in later periods
Influenced the development of both sacred and secular polyphonic genres
Cantus firmus practice
Use of a pre-existing melody, often from Gregorian chant, as the structural basis for a polyphonic composition
Cantus firmus typically placed in the tenor (lowest) voice
Upper voices composed to complement and elaborate on the cantus firmus
Technique used in various genres, including organum, motet, and early Mass settings
Allowed composers to create new works while maintaining connections to traditional repertoire
Imitation and canon
Imitation involves one voice repeating a melodic phrase introduced by another voice
Canon, a strict form of imitation, features exact repetition of a melody at a fixed time interval
Early use of imitation found in rounds and catch-like structures
More complex imitative techniques developed in motets and other polyphonic forms
Laid the groundwork for the pervasive use of imitation in Renaissance polyphony
Regional styles
Early polyphony developed distinct regional characteristics across Europe
Reflected local musical traditions, liturgical practices, and cultural influences
Contributed to the rich diversity of medieval polyphonic repertoire
French vs English polyphony
French polyphony
Characterized by intricate rhythmic structures and complex textures
Emphasized the use of isorhythm in motets and other forms
Influenced by the innovations of the Notre Dame school and Ars nova
English polyphony
Featured a preference for thirds and sixths in harmonic structures
Developed the "English discant" style with parallel motion in thirds and sixths
Gymel technique involved dividing a single line into two parallel parts
Italian lauda tradition
Laude were devotional songs in the vernacular Italian language
Originally monophonic but developed polyphonic settings in the 13th and 14th centuries
Often performed by lay confraternities outside of official liturgical contexts
Influenced the development of early Italian secular polyphony
Characterized by simpler textures and more accessible melodic styles compared to French polyphony
Secular polyphony
Development of secular polyphonic music paralleled that of sacred polyphony
Reflected the growing importance of courtly and urban musical cultures
Contributed to the evolution of vernacular song traditions and instrumental music
Troubadour and trouvère songs
Troubadours (southern France) and trouvères (northern France) composed monophonic songs in vernacular languages
Some songs were adapted into simple polyphonic settings
Polyphonic arrangements often featured added voices moving in parallel motion
Influenced the development of secular polyphonic forms like the chanson
Repertoire included various poetic and musical forms (virelai, ballade, rondeau)
Early madrigals
14th-century Italian secular polyphonic song form
Typically set for two or three voices with Italian texts
Often featured contrasting sections of melismatic and syllabic text setting
Incorporated both imitative and non-imitative contrapuntal techniques
Laid the groundwork for the more complex madrigals of the Renaissance period
Theoretical foundations
Medieval music theorists played a crucial role in codifying and explaining polyphonic practices
Theoretical writings provided a framework for understanding consonance, dissonance, and voice leading
Influenced compositional practices and the teaching of music in cathedral schools and universities
Treatises on polyphony
"Musica Enchiriadis" (c. 900) provided early descriptions of organum techniques
Guido of Arezzo's "Micrologus" (c. 1026) discussed various aspects of polyphonic composition
Johannes de Garlandia's "De mensurabili musica" (c. 1240) explained rhythmic modes and notation
Franco of Cologne's "Ars cantus mensurabilis" (c. 1280) further developed mensural notation
These treatises codified existing practices and influenced future developments in polyphonic composition
Concepts of consonance vs dissonance
Medieval theorists classified intervals as perfect consonances, imperfect consonances, or dissonances
Perfect consonances (unison, octave, fifth) were considered the most stable
Imperfect consonances (thirds, sixths) gained acceptance over time
Dissonances (seconds, sevenths, tritone) required careful treatment and resolution
Concepts of consonance and dissonance influenced voice-leading practices and harmonic progressions
Gradual acceptance of thirds and sixths as consonances shaped the development of tonal harmony
Transition to Renaissance
The late medieval period saw significant changes in musical style and theory
These developments laid the groundwork for the flourishing of polyphonic music in the Renaissance
Ars nova innovations
Term "Ars nova" coined by Philippe de Vitry, referring to new compositional and notational techniques
Introduction of duple meter alongside the established triple meter
Development of isorhythm, a technique using repeated rhythmic and melodic patterns
Expansion of available note values, allowing for more rhythmic complexity
Innovations in France paralleled by the Italian Trecento style
Influence on later styles
Ars nova techniques paved the way for the rhythmic flexibility of Renaissance polyphony
Isorhythm influenced structural approaches in both sacred and secular music
Expanded use of imitation led to the pervasive imitative counterpoint of the 15th and 16th centuries
Notational advancements enabled the composition and transmission of increasingly complex works
Secular forms like the formes fixes influenced the development of Renaissance chanson and madrigal
