20th-Century Music: Comprehensive Study Notes

Impressionism

  • Early defining stylistic entry into 20th-century music; paralleled Impressionist painting.

  • Aims:

    • Suggest reality rather than depict it literally.

    • Evoke moods, colors, atmosphere; emphasize light, water, nature.

    • Listeners receive an "impression" or emotional tint, not a detailed picture.

  • Musical traits (implied throughout lecture):

    • Subtle, shifting tonal centers; use of modes, whole-tone, pentatonic scales.

    • Delicate orchestration, blurred cadences, emphasis on timbre.

  • Representative works & composers:

    • Claude Debussy: La Mer, Clair de Lune (within Suite Bergamasque), Prélude à l’Après-midi d’un Faune.

    • Maurice Ravel: Jeux d’Eau, Daphnis et Chloé, Boléro.

    • Other national Impressionists: Ottorino Respighi (Italy), Manuel de Falla & Isaac Albéniz (Spain), Ralph Vaughan-Williams (England).

    • Won Prix de Rome 1884 with cantata L’Enfant Prodigue; spent 2 yrs study in Rome.

  • Stylistic innovations:

    • Evolved traditional rules into new possibilities of harmony (parallel chords, unresolved dissonance), rhythm (flexible, speech-like), form (free, episodic), texture (layered ostinati), orchestral color (novel instrument combinations).

    • Incorporated influences: Liszt’s virtuosity, Chopin’s piano idiom, Bach’s counterpoint, Verdi’s lyricism, Javanese gamelan (heard at 1889 Paris Exposition), Symbolist poetry.

    • Initially admired Wagner but later rejected excessive German chromaticism in favor of French subtlety.

  • Mature works (selection from approx. 227 total compositions):

    • Vocal: Ariettes Oubliées.

Comparative Styles of Debussy & Ravel

  • Sonic overlap: modal/whole-tone scales, coloristic orchestration, fluid textures.

  • Differences:

    • Form: Debussy spontaneous, free; Ravel meticulous, classical.

    • Motives: Debussy paints broad washes; Ravel develops motives with logical precision.

    • Imagery: Debussy evocative & casual; Ravel exacting, sometimes programmatic.

  • Transitional style: Late-Romantic works such as Verklärte Nacht 1899 blending Brahms lyricism with Wagner harmonic tension (tone poem for string sextet/orchestra).

  • Breakthroughs:

    • Freed dissonance from resolution (atonality, 1908–1920 period).

    2. Petrushka 1911 – polytonality, shifting meters portray puppet drama.

    3. The Rite of Spring 1913 – violent primitivism, asymmetrical rhythms, extreme dissonance; near abandonment of traditional tonality, caused premiere riot.

These notes interconnect stylistic developments of the 20th century: Impressionism’s coloristic genesis → Expressionism & Serialism’s abstraction → Primitivism’s rhythmic force → Neo-Classicism’s tempered return to order → Avant-Garde’s radical experimentation with electronics, minimalism, and chance. Each composer both reflected and propelled broader cultural, technological, and philosophical shifts of modernity.
