Comprehensive Notes on 20th Century Music: Impressionism to Electronic Music
20th Century Music: Historical and Cultural Factors
A product of modern technology (e.g., use of synthesizers, amplifiers, and recorders).
Context: music in the 20th century is shaped by technological advances and changing cultural landscapes (as reflected in the slides).
Impressionism in Music (1890s–1920s)
Definition and timeframe
French movement in the late 19th and early 20th centuries, spanning roughly 1890–1920, started amidst world war conditions.
Core idea
From the word “Impression,” the aim is to convey moods and atmospheres rather than depict literal reality.
Musicians and artists sought to evoke impressions or moods rather than concrete scenes.
Key characteristics
Use of Tone Color (timbre): emphasis on color and quality of sound.
Creating Atmospheric Qualities in Music: focus on mood and atmosphere; listening often feels like being transported to another place, real or imagined.
Unusual Chords: experimentation with harmony and sonorities.
Tone Color in Impressionism
“Timbre” or tone color is central; composers manipulate orchestration to create new color palettes.
Impressionist works often use dark colors through orchestration choices.
Notable term and example
Claire de Lune: French phrase meaning "moonlight" (moonlight).
Unusual chords and scale work
Debussy and other impressionists experimented with unconventional scales and chord progressions.
Whole Tone Scale: a scale in which each note is separated from the next by a whole tone (two semitones).
Formal definition:
A whole-tone scale can be represented as the pitch-class set
Interval between consecutive notes: (a whole step).
Popular song example cited as having used the whole tone scale: by Stevie Wonder.
Principal figures
Claude Debussy (French composer): principal exponent of Impressionism; reformer who shifted harmony, rhythm, form, texture, and color toward a new language.
Maurice Ravel (French composer): contemporary to Debussy; known for works with extensive chromaticism and color, often contrasted with Debussy’s approach.
Debussy: key points
Reformed musical development by eliminating traditional rules and conventions to explore new harmonic, rhythmic, formal, and textural possibilities.
Born August 22, 1862; Paris Conservatoire alumnus; regarded as a genius by his professors.
Ravel: key points
French composer known for virtuosic technique; works include Bolero, Jeux d’Eau (Water Fountains), La Valse, Daphnis et Chloe, String Quartet, and Rapsodie Espagnole.
Antonio Molina (Philippine context)
Filipino composer, conductor, and music administrator; named a National Artist of the Philippines for his services to music.
Referred to as the “Claude Debussy of the Philippines” for his use of impressionist themes in music.
Expressionism in Music
Definition and context
German movement focused on subjective experience and internal struggle.
Employed bold, often harsh dissonance and abstract form (content may be subordinated to emotion).
Goals
Capture the experience of being alive; express emotional experience rather than physical reality.
Expressionism also influenced dance, architecture, and cinema.
Key terms
Dissonance: lack of agreement or stability in harmony; produces clashing, less traditionally pleasing sonorities.
Notable figure (section overview)
Arnold Schoenberg: born in Vienna (September 13, 1874); 1874–1951. Self-taught in music theory, studied counterpoint; weakened tonality by developing the 12-tone serialism method; continued German tradition of reduced tonal clarity and polyphonic texture.
Works and concepts related to Schoenberg: Verklarte Nacht (Transfigured Night), Pierrot Lunaire, Gurre-Lieder.
Arnold Schoenberg and Serialism
Biography and approach
Born in a working-class Vienna suburb; life spanned 1874–1951.
Largely self-directed in music theory; pursued counterpoint studies.
Emerged as a pivotal figure in the move away from tonal centers toward serialist techniques.
Musical innovations
Weakened tonality and introduced the 12-tone serialism method of composition.
Continued the German tradition of reduced tonal emphasis and polyphonic texture.
Selected works
Verklarte Nacht (Transfigured Night) – originally a one-movement string sextet for two violins, two violas, and two cellos; later arranged for string orchestra.
Pierrot Lunaire – a landmark song cycle consisting of 21 songs arranged in three groups of seven poems.
Gurre-Lieder (Gurre-Lieder) – a large-scale vocal-orchestral work.
Pierrot Lunaire details
Means “Moonstruck Pierrot”; embodies the motif of a Pierrot who wears a mask to conceal inner feelings or opinions.
The work is structured into three groups of seven poems, exploring themes of love, violence, blasphemy, and haunting memories.
Igor Stravinsky and The Rite of Spring
Profile
Russian composer active in Paris; associated with nationalist and modernist tendencies.
Major works discussed
The Rite of Spring (Le sacre du printemps) – ballet and orchestral work premiered in 1913 in Paris; later presented as a concert work (1919).
The Firebird Suite – derived from his earlier ballet The Firebird (1909–1910); Suite released in 1910.
Historical significance of Rite of Spring
The premiere caused a famed audience riot; noted for its radical musical language and choreography that evoked primitive vitality.
The score introduced unprecedented rhythmic complexity and dissonance, challenging traditional musical expectations.
Other features
Early Stravinsky works show influence from his teacher Nikolai Rimsky-Korsakov.
Notable score details (from the slides)
Rite of Spring sections include movements such as “The Augurs of Spring,” “Dances of the Young Girls,” and other numbered sections (I–VIII in the score excerpt shown).
The work is presented both as a ballet and an orchestral concert piece.
Tonal vs. Atonal Music
Tonal music
Structured around a central key or tonal center; certain notes or chords are perceived as stable or “home.”
Atonal music
Deliberately avoids establishing a key or tonal center; treats all notes with equal importance.
Modernism in Music
Characteristics and scope
A broad movement in which traditional boundaries of music were questioned or redefined.
Included the use of noises and nontraditional sounds as legitimate musical materials (e.g., airplane swooshes, water sounds).
Electronic and technological emphasis
Involved electronically created sounds and the use of electronic means to reproduce or generate music for public performances.
Production could involve computer installations and microphones, with recordings enhanced to achieve the desired result.
Electronic Music: Instruments and Pioneers
What is electronic music?
Music that employs electronic instruments and technology in its production.
Early electronic sound sources mentioned
Telharmonium, Hammond organ, electric guitar (as examples of pre- and early-electronic instruments).
Key 20th-century figures

Other Notable Electronic and Mixed-Media Works
Festino; Synchronism; Electronic Studies; Duo Capriccioso
Series of works expanding chamber music by incorporating electronic components and live performance.
Conceptual emphasis
Pushed boundaries of what could be considered music by blending technology with acoustic performance.
Aleatory (Chance) Music and Indeterminacy
Terminology and concept
Also known as Aleatory music or Chance Music.
The composition or performance contains elements of unpredictability, such as random selections of pitches and rhythms.
Some choices are left to the performers; the music may change with each performance.
Pioneering figures
John Cage: American composer, music theorist, writer, and artist; advocated indeterminacy in music, electroacoustic techniques, and non-traditional instrument usage.
4’33” by John Cage
A three-movement composition instructing performers to remain silent for the duration of the piece, typically four minutes and thirty-three seconds.
Reinterprets the concept of music as ambient sound and listener perception rather than intentional performance of organized sound.
Significance
Challenges conventional definitions of music and performance; emphasizes listening and the role of chance, environment, and audience in a musical experience.
Summary of Key Concepts and Connections
Impressionism centered on mood, atmosphere, tone color, and novel scales (like whole-tone), replacing strict, traditional tonal rules with coloristic and impressionistic effects.
Expressionism pursued intense emotional experience, often through dissonance and abstract forms, influencing art beyond music (dance, architecture, film).
Serialism (Schoenberg) disrupted traditional tonality, introducing systematic organization of pitch (12-tone) as a method to structure music without a fixed key.
Stravinsky’s Rite of Spring exemplified radical rhythm, harmony, and orchestration that disrupted audience expectations and highlighted modernist themes.
Modernism embraced sounds previously considered non-musical (noise) and expanded beyond traditional performance to electronic and spatial music.
Electronic music integrated electronic instruments and technology, with key pioneers expanding the palette of timbres and textures available to composers.
Synchronism and other mixed works demonstrated how live performers could be paired with tape and electronic sounds to create new sonic experiences.
Aleatory and indeterminacy challenged the idea of fixed, deterministic musical outcomes, shifting some creative control to chance and performer input.
Throughout these movements, cross-pertilization occurred among philosophy, technology, and aesthetics, influencing not just music but broader culture and real-world applications.
