20th-Century Music Study Notes

Music of the 20th Century

Broad Context & Overarching Themes

  • The century witnessed unprecedented diversity, experimentation, and global cross-pollination in musical language.
  • Technological breakthroughs (radio, recording tape, vinyl, cassette, CD, synthesizer, computer) reshaped both composition and consumption.
  • Music mirrored the century’s cultural shifts: two World Wars, decolonization, the Cold War, civil-rights movements, and rapid industrial/technological change.
  • Overall arc: move from common-practice tonal harmony toward atonality, new timbres, electronic sources, and free forms.
  • Philosophical implication: art no longer bound to please; it could question, shock, or simply exist as sound-in-time.

Major Transformations & Innovations

  • Expansion of harmony: from late-Romantic chromaticism to atonality and serialism.
  • Rhythmic evolution: asymmetrical meters, polyrhythms, ostinati, additive rhythms.
  • Timbre foregrounded as an independent musical parameter.
  • Global folk traditions actively folded into “art” music (= modern nationalism).
  • Rise of sound recording turned performance into a reproducible object; studio became a compositional tool.

Principal 20th-Century Styles

  • Impressionism
  • Expressionism
  • Primitivism
  • Neoclassicism
  • Avant-Garde / Experimentalism
  • Electronic Music (often grouped within the Avant-Garde)
  • Chance (Aleatoric) Music
  • Modern Nationalism

Impressionism

  • Origin: late-19th19^{\text{th}}-century France; musical parallel to Monet, Renoir, etc.
  • Aims: evoke mood & atmosphere, paint with sound rather than outline clear structures.
  • Hallmarks:
    • Whole-tone, pentatonic, modal scales.
    • Parallel chords (“planing”), unresolved dissonances.
    • Subtle orchestration—harp glissandi, muted strings, coloristic woodwinds.
    • Ambiguous tonality; blurred rhythmic pulse.
Claude Debussy (1862-1918)
  • Pioneering figure; rejected traditional development sections in favor of “tone-pictures.”
  • Signature works & significance:
    • “Clair de Lune” – dream-like piano miniature; exemplifies soft dynamics and parallel harmony.
    • “Prélude à l’Après-midi d’un faune” – orchestral tone poem; opened door to modernism via fluid meter and exotic scales.
  • Legacy: Expanded harmonic vocabulary, inspired film scoring, jazz harmonies, ambient music.
Joseph Maurice Ravel (1875-1937)
  • French composer/pianist/conductor; meticulous craftsman.
  • Though linked to Impressionism, preferred the label “neoclassic colorist.”
  • “Boléro” – single orchestral crescendo built on repeating two-bar rhythm; demonstrates orchestration as form.
  • Synthesized styles: Spanish dance rhythms, jazz harmonies, Baroque forms.
  • International celebrity in 19201920s-19301930s; directly influenced Gershwin, Britten, jazz arrangers.

Expressionism

  • Geographic center: German-speaking lands, early 20th20^{\text{th}} century.
  • Goal: expose inner angst, psychological extremes.
  • Techniques:
    • Intense dissonance, abrupt contrasts, angular melodies.
    • Atonality ⇒ rejection of tonal center.
    • Later codified into 12-tone serialism (= ordered row of the 1212 chromatic pitches).
Arnold Schoenberg (1874-1951)
  • Broke with tonality circa 19081908 (“free atonality”).
  • Developed serial method (\textit{Zwölftontechnik}) ≈1921\approx 1921, empowering systematic atonal writing.
  • Importance: Provided composers new structure once tonal gravity abandoned.
  • Philosophical weight: Emancipation of the dissonance; music as expression of subconscious.

Primitivism

  • Seeks raw power of ancient/tribal cultures; rhythm and color central.
  • Traits: driving ostinati, polymeter, harsh orchestration, folk-like melodies.
Igor Stravinsky (1882-1971)
  • “The Rite of Spring” (prem. 19131913) – landmark ballet; pounding accents, bitonality incited historic riot.
  • Brought rhythmic innovation into mainstream modernism.
Béla Bartók (1881-1945)
  • Hungarian modernist & ethnomusicologist; collected >8{,}000 folk tunes.
  • Integrated additive folk rhythms & modal scales into sophisticated art music.
  • Stood alongside Schoenberg, Berg, Webern, Stravinsky, Varèse as early-modernist elite.

Neoclassicism

  • Reaction against perceived excess of Romanticism & Expressionism.
  • Returns to balance, clarity, formal order of 18th18^{\text{th}}-century masters, yet w/ modern harmony & rhythm.
Sergei Prokofiev (1891-1953)
  • Versatile Russian composer.
  • Combines classical forms with motoric rhythms & sharp dissonances.
  • Signature work: “Peter and the Wolf” – orchestral fairy-tale assigning each animal an instrument.
  • Output: 77 symphonies, ballets (“Romeo and Juliet”), film scores (“Alexander Nevsky”).
Francis Poulenc (1899-1963)
  • Member of “Les Six”; sought clarity & urban chic.
  • Hallmarks: witty melodies, transparent textures, sudden emotional depth.
  • Balances playful works (woodwind sonatas) with sacred masterpieces (“Gloria”).

Avant-Garde / Experimental Music

  • Umbrella for composers who challenged the very definition of music.
  • Guiding ethos: “Be ahead of one’s time.”
John Cage (1912-1992)
  • Expanded concept of musical sound to include silence & ambient noise.
  • Landmark piece: 4′33′′4^{\prime}33^{\prime\prime} – performer tacets; audiences hear environmental sounds.
  • Advocated “purposeful purposelessness.”
Karlheinz Stockhausen (1928-2007)
  • German pioneer of electronic & spatial music.
  • Employed ring modulators, tape loops, and multi-speaker diffusion (e.g., “Gesang der Jünglinge”).
  • Controversial but pivotal in electronic studio technique.
Edgard Varèse (1883-1965)
  • Dubbed “Father of Electronic Music.”
  • Conceived music as “organized sound”; utilized sirens, percussion, tape (e.g., “Poème électronique”).

Electronic Music

  • Grew alongside post-WWII technology: tape recorders, sine-wave generators, Moog & Buchla synths, MIDI, DAWs.
  • Processes: splicing, reversal, speed manipulation, filtering, additive/subtractive synthesis.
  • Early centers: Paris (Musique Concrète), Cologne (Elektronische Musik), New York (Columbia-Princeton).
  • Key pioneers overlap with Avant-Garde list: Varèse, Stockhausen, Cage; later expanded to popular genres (Kraftwerk, EDM).

Chance (Aleatoric) Music

  • Some compositional decisions delegated to random procedures (dice, I-Ching) or performers’ choice.
  • Philosophical underpinning: acceptance of unpredictability; parallels to Zen, quantum indeterminacy.
  • Cage’s later works (“Music of Changes”) prime examples.

Modern Nationalism

  • Renewed interest in folk heritage as political borders shifted.
  • Methods: quote folk tunes, emulate folk scales/modes, mimic traditional instruments.
  • Representative composers:
    • Béla Bartók – Hungary (field recordings fused into string quartets, piano works).
    • Sergei Prokofiev – Russia (incorporated folk motives and stark dissonance).

Ethical, Philosophical & Practical Implications

  • Democratization of sound: anyone with tape or later a laptop can create.
  • Questions of authorship (who “composes” in aleatoric works?).
  • Intellectual property & sampling debates sparked by electronic manipulation.
  • Music as social commentary: e.g., Stravinsky’s pagan ritual, Shostakovich’s coded dissent (contextual relevance though beyond given slides), Cage’s environmental awareness.

Key Takeaways / Exam Tips

  • Be able to match each style with its principal traits & representative composers.
  • Recognize that some composers (e.g., Bartók, Prokofiev) straddle multiple categories (Primitivism, Neoclassicism, Modern Nationalism).
  • Understand technological milestones (tape, synthesizer) and their artistic consequences.
  • Memorize hallmark works (e.g., Debussy’s “Clair de Lune,” Stravinsky’s “Rite,” Cage’s 4′33′′4^{\prime}33^{\prime\prime}) and why they’re iconic.
