20th-Century Music – Comprehensive Study Notes

Overview of Early–Mid 20th-Century Musical Styles

• Radical break from 19th-century Romantic conventions → rise of clearly branded styles.
• Core stylistic families taught in Grade 10:
– Impressionism
– Expressionism
– Primitivism
– Neo-Classicism
– Avant-Garde
– Nationalism/Ethnicism/Exoticism
– Electronic music / Musique Concrète
– Chance (Aleatoric) music
• Leading composers came from France, Austria, Hungary, Russia & USA—showing globalisation of art music.

Impressionism (France, late-19th–early-20th C.)

• Earliest concrete sign of 20th-century sound.
• Musical equivalent of the visual art movement: colour, atmosphere, suggestion, not precise outline.
• Hallmarks
– Extensive colour/timbre effects; orchestral “painting.”
– Vague, fluid melodies; avoidance of clear cadences.
– Innovative chords, modes & progressions ⇾ mild dissonance.
– Use of whole-tone, pentatonic & church modes; parallel chords.

Major Proponents

• Claude Debussy (1862-1918) — “Father of the Modern School of Composition.”
• Maurice Ravel (1875-1937).

Claude Debussy

• Born St-Germain-en-Laye, 22 Aug 1862; died Paris, 25 Mar 1918 (cancer).
• Early training: piano lessons → Paris Conservatory (1873).
• Reputation: erratic pianist, rebel theorist; admired Liszt, Chopin, Bach, Verdi, Wagner.
• Prix de Rome winner (1884) with $L'Enfant\ Prodigue$; Roman residency exposed him to Wagner’s $Tristan\ und\ Isolde$ yet he rejected grandiose style.
• Fascinated by Javanese Gamelan (Paris Exposition 1889) → non-Western sonorities.
• Output ≈ 227 works: orchestra, chamber, piano, opera, ballet, songs.
• Signature pieces & creative phases
– $Prélude\ à\ l'Après-midi\ d'un\ Faune$ (tone poem).
– String Quartet (early chamber cornerstone).
– $Pelléas\ et\ Mélisande$ (1895) — controversial opera for harmonic/textural novelty.
– $La\ Mer$ (1905) — atmospheric “symphonic sketches” of the sea.
– Piano cycles: $Images$, $Suite\ Bergamasque$ (contains “Clair de Lune”), $Estampes$.

Maurice Ravel

• Born Ciboure, France; Basque mother, Swiss father; Paris Conservatory age 14 (studied under Gabriel Fauré).
• Style traits
– Innovatively harmonic yet generally tonal (rarely atonal).
– Intricate, modal or extended melodies; lush extended chords.
– Demands virtuosity (virtuoso = performer of exceptional skill).
– Frequent water imagery; keen human character sketches.
• Key works
– $Pavane\ pour\ une\ Infante\ Défunte$ (1899) — slow lyrical memorial.
– $Jeux\ d'Eau$ (1901) — sparkling piano fountains.
– String Quartet (1903).
– $Sonatine$ (c. 1904).
– $Miroirs$ (1905) — harmonic imagination.
– $Gaspard\ de\ la\ Nuit$ (1908) — notoriously difficult piano trilogy.
– $Valses\ Nobles\ et\ Sentimentales$ (1911).
– $Le\ Tombeau\ de\ Couperin$ (c. 1917) — homage to Baroque.
– $Rhapsodie\ Espagnole$; $Boléro$ (orchestral crescendo built on an ostinato).

Debussy vs Ravel

• Debussy = spontaneous, liberal forms; free visual impression.
• Ravel = meticulous, classical structures; rigorous motive development.
• Both share lush harmony & colour, but differ in personality and craft approach.

Expressionism (early 20th C.)

• Music as medium for strong, often disturbing emotions; reveals the composer’s inner psyche instead of external impressions.
• Typical sound: extreme dissonance, wide leaps, angular lines, atonality.

Arnold Schoenberg (1874-1951)

• Born Vienna, self-taught theory; influenced by Wagner ($Pelléas\ und\ Mélisande$ symphonic poem, 1903).
• Stylistic evolution
– Late-Romantic tonality → heightened chromaticism → atonality (absence of key centre).
– Pioneered the Twelve-Tone (Dodecaphonic) System.

Dissonant & Atonal Concepts

• Traditional tonal songs possess a perceivable “tono”; listeners can hum along.
• Atonal music removes this gravitational centre; pitches appear equal.
• Schoenberg’s audiences met his works with hostility because $\text{TONALITY}$ dominated popular taste.

12-Tone Method

• Utilises all $12$ chromatic pitches {C,\ C#,\ D,\ D#,\ E,\ F,\ F#,\ G,\ G#,\ A,\ A#,\ B} exactly once before any repeats → tone-row.
• Row can undergo transformations: prime $P<em>0$, retrograde $R$, inversion $I$, retrograde-inversion $RI$; each may start on any transposition $T</em>n$.
• Premise: “all notes are created equal” → emancipation from tonal hierarchies.

Igor Stravinsky (1882-1971)

• Born Lomonosov, Russia (17 Jun 1882); pupil of Nikolai Rimsky-Korsakov.
• Mentioned alongside cultural trendsetters Picasso & James Joyce.
• First major success: The Firebird Suite (1910) — surpassed Russian predecessors.
• Music characteristics
– Shocking modernity, but highly structured, precise, controlled.
– Emphasis on artifice & theatricality.
• Key ballets
– Petrouchka (1911): shifting metres, polytonality.
– The Rite of Spring (1913): dissonant, atonal moments; asymmetrical rhythms; depiction of pagan ritual.

Primitivism / Nationalism / Exoticism

• Combines simple, often folk-based ideas to forge new sounds.
• Bitonality, unusual instruments, modal scales create “raw” sonorities.
• Terminology
– Exoticism: borrow from a foreign culture e.g. American melody + French accordion.
– Nationalism: use of indigenous material e.g. American tune + ukulele.
– Ethnicism: draw from European ethnic groups (e.g., gamelan with Western ensemble).

Béla Bartók (1881-1945)

• Born Nagyszentmiklós, Hungary (now Romania), 25 Mar 1881; mother was first piano teacher; entered Budapest Royal Academy (1899).
• Wrote nationalist symphonic poem Kossuth (1903) – tribute to Lajos Kossuth (revolutionary hero).
• Collected ≈ 20 Hungarian folk songs initially rejected at home, yet persisted in field research → over 700 compositions.
• Stylistic traits
– Changing metres, strong syncopation.
– Rich modal melodies, lively folk rhythms.
• Representative pieces
– Six String Quartets — difficult, dissonant, mysterious.
– Concerto for Orchestra (1943) — 5-movement, intricately constructed.
– Allegro Barbaro — piano solo with swirling rhythms & percussive chords.
– Mikrokosmos — 6 books, 153 graded piano studies; contemporary harmony/rhythm.
– Duets for Pipes (et al.).

Neo-Classicism (c. 1920-1950)

• “Throwback” blending Classical-period clarity with modern harmony.
• Juxtaposes Romantic/Expressionist colour vs Classical form; tonal vs dissonant; structured vs free.

Sergei Prokofieff (1891-1953)

• Born Sontsovka, Ukraine; studied St Petersburg Conservatory.
• Early avant-garde works shocked elders → emigrated seeking acceptance; wrote ballets & operas.
• Ballet highlight: Romeo & Juliet.
• Opera highlight: War & Peace (unfinished, performer resistance).
• Wrote cheerful educational orchestral tale Peter and the Wolf to appease authorities.
• Symphony No. 1 “Classical” evokes Haydn/Mozart with Stravinskian twist.

Francis Poulenc (1899-1963)

• Wealthy Parisian family wanted business career; largely self-taught; member of Les Six (group rejecting Romanticism & Impressionism; admired Stravinsky).
• Instrumental
– Concert Champêtre (1928) — harpsichord concerto, “pastoral.”
– Concerto for Two Pianos (1932): Mozart-like clarity + Ravel-like exoticism (written in 3 months).
– Concerto for Solo Piano (1949).
• Vocal stage works
– Les Mamelles de Tirésias (1944): comic opera; woman becomes male; social satire.
– Dialogues des Carmélites (1956): nuns martyred, sombre guillotine scene.
– La Voix Humaine (1958): one-woman telephone monodrama, implied suicide.
• Choral
– Litanies à la Vierge Noire (1936): monophony, simple harmony, startling dissonance.
– Stabat Mater (1950): Baroque solemnity (“the sorrowful mother stood”).

Avant-Garde

• Music born from experimentation; critiques existing aesthetics; rejects mainstream; intentionally provocative.
• Perception adjectives from slides: “weird, alien-like, ugly, not a trend, costumes.”
• Idea: push boundaries—today’s avant-garde may become tomorrow’s normal.

George Gershwin (1898-1937)

• Born Brooklyn, New York, to Russian-Jewish immigrants.
• First song (1916); first Broadway musical La La Lucille (1919).
• Style: half-jazz, half-classical ⇾ crossover artist; dubbed “Father of American Jazz.”
• Masterpieces
– Rhapsody in Blue (1924): premiered in “An Experiment in Modern Music,” Aeolian Hall, with Gershwin as soloist.
– An American in Paris (1928).
– Porgy and Bess (1934): folk opera now Broadway staple.
• Legacy: merged classical & jazz; bridged Europe ↔ America; classical ↔ commercial; commercial success.

Leonard Bernstein (1918-1990)

• Born Massachusetts; charismatic conductor & composer.
• 14 Nov 1943: unexpectedly replaced Bruno Walter at NY Philharmonic → instant acclaim as interpreter.
• Philosophy: music’s universal language is fundamentally tonal, opposing mid-century serialists.
• To defend tonal ideals he expanded into conducting & lecturing (notably “Harvardian Lectures”).
• Twin career peaks
– Conducting — NY Philharmonic, worldwide podiums.
– Composing — Broadway & concert:
• West Side Story (1957) — modern “Romeo & Juliet.”
• Candide (1956).
• On the Waterfront (1954).
• Mass (1971).

Electronic Music

• New tech revolutionised sound production; uses electronic instruments & devices.
• Typical tools: synthesizers (e.g., Roland JD-XI pictured).
• Musique Concrète — manipulates recorded tape fragments; pioneered in 1940s Paris.

Edgard Varèse (1883-1965)

• “Father of Electronic Music”; earliest tape-based composer.
• Landmark work Poème Électronique (1958) — spatialised sound-sequence in Philips Pavilion.

Chance (Aleatoric) Music

• Composition/interpretation left to chance; every performance differs; cannot be duplicated.
• Iconic piece: John Cage’s $4'33''$ — performer tacet, ambient sounds become the music.

Key Numerical / Theoretical References

• Chromatic scale = $12$ distinct semitones per octave.
• Twelve-tone row notation: ${P<em>0,\ P</em>1,\dots,\ P_{11}}$ with operations $R,\ I,\ RI$.
• Bartók: 700+ catalogued works; Mikrokosmos = 6 books, 153 pieces.
• Prokofieff’s Concerto for Orchestra = 5 movements.
• Bernstein’s West Side Story premiere year $1957$.

Ethical / Philosophical / Practical Implications

• Modernism challenged audiences; hostility toward atonality shows tension between innovation & acceptance.
• Avant-garde’s “ugliness” debate teaches tolerance for non-normative art.
• Cage’s chance music redefines authorship & listening — the environment (and audience) co-creates sound.
• Electronic tools democratise sound creation; raises questions on authenticity & performer role.

Connections & Real-World Relevance

• Impressionist colour still influences film/game scoring for atmosphere.
• Twelve-tone & serial techniques underpin much 20th-century academic music, shaping modern conservatory curricula.
• Jazz-classical fusion anticipated contemporary genre-blending (e.g., hip-hop orchestral projects).
• Synthesizers & electronic production dominate today’s pop, EDM, movie sound design.
• Chance principles echo in generative music apps & AI-driven composition.
