Notes on 20th Century Music Movements: Impressionism to Chance Music

Musical Elements

  • TEMPO

    • It refers to the orderly flow of movement in music which makes it alive.

  • RHYTHM

    • It is an organized succession of tones with different durations and pitches. It also known as the “tune”.

  • DYNAMICS

    • It is the loudness and softness of sound/ music.

  • MELODY

    • It is the organized combination of tones. It is also refers to the vertical or chordal structure of a musical work.

  • TEXTURE

    • It is the characteristic of a musical melody and harmony which also known as the overall structure of a composition.

  • HARMONY

    • It refers to the design or shape of music which a composer follows.

  • TONE COLOR

    • This refers to the quality of tone.

  • FORM

    • It is the organized flow (design) of music which a composer follows.

20th Century Music Overview

  • The twentieth century is one of the most complex times of all the historical periods. Changes have been fast and dramatic in all areas of culture: social, political, scientific, technology, economics or even music.

  • Music embraced new forms, sounds, and technologies; composers began to experiment with melody, harmony, rhythm, tempo, and timbre to create novel sound worlds.

  • Electronic devices such as synthesizers, cassette tape recorders and Android phones were used to create and record music.

Impressionism

  • Definition and origins

    • A movement in painting (started in France in the $1860$s) with a musical counterpart that sought to convey moods and impressions rather than exact realities.

  • Musical characteristics

    • Use of timbre (colors) and a focus on the fluidity of color and light in sound; extensive use of different timbres.

    • New chords and progressions; use of whole tone, pentatonic ($5$-note scale), and chromatic scales ($
      octave").

    • Goal: to evoke mood and atmosphere rather than depict literal reality; the idea of suggesting reality rather than detailing it.

  • Important figures and works

    • Claude Debussy (1862–1918): primary exponent of impressionism; dissolved traditional rules to explore harmony, rhythm, form, texture, and color.

    • Debussy compositions associated with impressionism include:

    • "Claire de lune" ($1862$–$1918$)

    • "Le Petit Nègre" ($1862$–$1918$)

    • "Golliwogg’s Cakewalk" ($1862$–$1918$)

    • He is viewed as a catalyst for new musical possibilities and a focal point for other impressionist composers.

  • Debussy and Ravel (as impressionists)

    • Debussy: transformed harmony and texture; emphasized color and atmosphere.

    • Joseph Maurice Ravel (born in Ciboure, France to a Basque mother and Swiss father) studied at the Paris Conservatory from age 14 under Gabriel Fauré; his harmonic language was innovative and innovative but not atonal.

  • Significance

    • Impressionism represented a shift away from Romantic tonal centers toward coloristic orchestration and atmospheric painting of sound.

    • It laid groundwork for later explorations of timbre and scale (whole tone, pentatonic).

Expressionism

  • General description

    • Usually used in visual and literary arts; probably first applied to music in $1918$, especially in the works of Schoenberg.

    • A traditional form of beauty gave way to conveying powerful, often disturbing, feelings in music.

  • Key musical characteristics

    • A high degree of dissonance (unstable sound) and lack of traditional harmony.

    • Extreme contrasts of dynamics (from pp to ff).

    • Expression of strong emotions such as rage, anxiety, and alienation.

    • Lacks stable and conventional harmonies; constantly changing textures (monophonic, homophonic, polyphonic).

    • Distorted melodies and harmonies; extremes of pitch; few cadences (less finality and predictable progression).

  • Important figures

    • Arnold Schoenberg (born $1874$) was a primary exponent of expressionism and is credited with the development of the twelve-tone system (which transforms pitch organization).

  • Significance

    • Pushed music beyond traditional tonality and form, embracing atonality and systematic methods (like twelve-tone technique) to express psychological extremes.

Primitivism

  • Core idea

    • A movement that valorized “primitive” or ancient, raw, rudimentary artistic energies and ideas; often depicted scenes from earlier times or distant places.

  • Musical characteristics

    • Syncopation (off-beat accents) and strong accents to convey power.

    • Extensive use of percussion; traditional instruments (strings, winds, brass) used in new ways to create percussive textures.

    • The belief that primitive stories and ideas should be explored as foundational or ancestral; a respect for early music and myth.

  • Notable figure

    • Igor Stravinsky (1882–1971): Russian composer who later became French and American; his works blended primitive energy with modern techniques.

  • Stravinsky’s style and contributions

    • Stravinsky combined traditional and modern trends, contributing to primitivism as well as other movements (expressionism, neo-classicism).

  • Significance

    • Introduced rhythmic vitality, stacked layers, and novel orchestration that challenged conventional expectations of form and rhythm.

Neo-Classicism

  • Concept

    • A return to an earlier stylistic framework (Classical period) reinterpreted with a modern sensibility: clarity, balance, emotional restraint.

    • Combined tonal harmonies with slight dissonances; a modern free use of the seven-note diatonic scale.

  • Representative figures

    • Bela Bartók (1881–1945): Hungarian composer, pianist, and ethnomusicologist who integrated Hungarian folk tunes into his music; a leader of nationalistic neo-classicism.

    • Igor Stravinsky is also associated with neo-classicism (alongside primitivism and other roles).

    • Sergei Prokofiev (Russian/Soviet) is described as a Neo-classicist, nationalist, and avant-garde composer, known for progressive technique, pulsating rhythms, direct melodic lines, and occasionally resolving dissonances.

  • Significance

    • A cross-pertilization of classical form with modern harmonic language; a usable, accessible approach that retained traditional structures while embracing new colors and rhythms.

Avant-Garde

  • Definition

    • A movement of new and unusual ideas in music, often linked to experimentation that challenges conventions.

  • Characteristics

    • A new attitude toward musical form and continuity; variation in the order of note groups; improvisation as a necessity; scores may not be followed exactly as written.

  • Notable figures commonly associated

    • Francis Poulenc, George Gershwin, Leonard Bernstein, Philip Glass (as listed in the source), among others.

  • Significance

    • Pushed the boundaries of what could be considered music, introducing unconventional techniques, timbres, and performance practices.

Modern Nationalism

  • Concept

    • A looser form of 20th-century development focused on nationalist composers and musical innovators who combined modern techniques with folk materials.

  • Elements

    • Use of musical ideas identified with a country/region/ethnicity, including folk tunes, rhythms, and harmonies inspired by them.

  • Significance

    • Helped preserve and valorize cultural identities within a modern, global music landscape; a bridge between tradition and innovation.

Electronic Music

  • Core idea

    • The capacity of electronic machines (synthesizers, amplifiers, tape recorders, loudspeakers) to create, manipulate, and shape sounds.

  • Pioneers and contributors

    • Karlheinz Stockhausen (German). Electronic music and musique concrète specialist.

    • Edgard Varèse (often called the “Father of Electronic Music”).

  • Significance

    • Opened entirely new sonic worlds; expanded sound palettes beyond traditional acoustic instruments; introduced new methods of recording, processing, and performance.

Chance Music

  • Definition

    • A style in which the piece can sound different at every performance due to random techniques and the incorporation of external sounds.

    • Sounds often originate from surroundings (natural and man-made): honking cars, wind, leaves, dripping water, ringing phones, etc.; these elements cannot be exactly duplicated because they occur by chance.

  • Proponent

    • John Cage (composer associated with chance music and indeterminacy).

  • Significance

    • Emphasized process over fixed sonic results; questioned composers’ control over outcomes; foregrounded randomness and environment as an essential musical component.
