10/11 10. Contemporary, Popular, and Global Musical Cultures

A Framework for Music after 1945

Music after 1945 expanded both the materials of music and the ways musical works could be organized. Instruments and voices remained important, but composers and performers also used recorded sounds, electronic tones, environmental noise, synthesizers, computers, digital sampling, and studio processing.

Four questions provide a useful framework:

1. What is the sound made from? Consider instruments, voices, recorded sounds, electronic tones, samples, and environmental noise.

2. How is the music organized? Listen for fixed notation, repetition, improvisation, chance, beat-based structures, song forms, and studio processes.

3. Who controls the result? Control may belong to the composer, performer, producer, recording engineer, audience, or several of these together.

4. What setting gives the music meaning? A concert hall, club, cinema, religious ceremony, street, dance floor, protest movement, or digital platform can shape how music functions.

The period also blurred boundaries between art music and popular music. Radio, recordings, television, film, synthesizers, and digital technologies changed how music was produced, distributed, and heard. African American traditions such as rock, soul, funk, jazz, and hip-hop became central forces in global popular music.

Takeaway: Postwar musical culture is best understood through sound, organization, authorship, technology, and cultural context rather than through genre labels alone.

Electronic and Electroacoustic Sound

Electronic music uses technology to create, transform, record, or reproduce sound. In Paris, Pierre Schaeffer developed Musique concrète, which began with recorded sounds such as trains, voices, or percussion. These sounds could be edited, spliced, reversed, filtered, and reorganized until recognizable noises became rhythm, timbre, or texture.

At the WDR studio in Cologne, Elektronische Musik initially emphasized electronically generated tones, especially sine waves and carefully controlled combinations of frequencies. The two approaches gradually converged as composers combined recorded and synthesized sounds.

The studio became a musical instrument, while tape or a computer file could function as a fixed plan for a work that could be replayed without a live performer. Important examples include:

• Pierre Schaeffer’s Étude aux chemins de fer uses recordings of trains as musical material.

• Karlheinz Stockhausen’s Gesang der Jünglinge combines a boy’s voice with electronic sounds, moving between intelligible speech and abstract sonority.

• Milton Babbitt’s Philomel integrates a live soprano with prerecorded and electronically processed sound.

• Wendy Carlos’s Switched-On Bach demonstrates how synthesizers could reinterpret familiar Baroque music for popular listening.

When listening, ask whether a sound is acoustic, electronic, or processed; whether its source is recognizable; and whether echo, filtering, distortion, or spatial movement functions as part of the composition.

Takeaway: Electronic music treats sound itself as compositional material, often making the recording or studio central to the musical work.

Chance, Indeterminacy, and New Notations

Indeterminacy allows some aspect of a performance to remain open. A performer may choose pitches, durations, order, dynamics, or gestures, so different performances can produce different musical results. Chance music uses random procedures to determine some compositional decisions.

These practices challenge the assumption that every musical work must have one completely fixed sonic identity. John Cage used chance operations, unconventional instruments, silence, environmental sound, and alternative notation. In 4′33″, the performer does not intentionally produce the customary instrumental sounds, directing attention toward the surrounding environment and the act of listening.

Representative examples include:

• Music of Changes by John Cage uses chance procedures to determine musical events.

• Projection 1 by Morton Feldman uses graphic notation that gives performers controlled but flexible choices.

• December 1952 by Earle Brown presents visual elements that may be interpreted in different ways.

To compare a fixed work with an open-form work, listen for whether the sequence of events stays the same, whether durations change, whether performers make audible decisions in real time, and whether silence functions as absence, preparation, or musical material.

Takeaway: Indeterminate music shifts some responsibility for the final result from the composer’s fixed instructions to performers, chance, and the listening environment.

Minimalism and Process

Minimalism emerged prominently in American experimental music during the 1960s. Its characteristic techniques include repetition, steady pulse, limited harmonic materials, gradual transformation, additive or subtractive processes, drones, and phase shifting. Instead of relying mainly on dramatic contrast, minimalist music often asks listeners to perceive small changes within a stable pattern.

Early figures include La Monte Young, Terry Riley, Steve Reich, and Philip Glass. Their work was influenced by Indonesian gamelan, Indian classical music, African rhythmic practices, jazz, and American popular music. Gamelan is especially notable for its interlocking parts, cyclical organization, layered metallic timbres, and coordinated ensemble performance.

Examples show different kinds of process:

• Terry Riley’s In C uses short patterns that performers repeat in varying quantities and orders within broad guidelines.

• Steve Reich’s It’s Gonna Rain uses tape loops that gradually move out of phase, creating changing rhythmic patterns.

• Reich’s Music for 18 Musicians combines steady pulse, repeating patterns, shifting harmonies, voices, percussion, and audible connections between sections.

• Philip Glass’s Einstein on the Beach uses repeating figures, additive processes, vocal numbers, and recurring “knee plays” in a large-scale music-theater work.

• John Adams’s Short Ride in a Fast Machine extends minimalist pulse and repetition into a colorful, dramatic orchestral language.

On repeated hearings, track the recurring pulse, the length and shape of motives, changes in register and orchestration, displaced accents, and moments when a long process produces a sudden textural change.

Takeaway: Minimalist listening depends on following process: repetition creates stability, while gradual change creates direction.

Postmodernism and Musical Pluralism

Postmodernism in music is not one unified style. It is an attitude toward musical history and cultural boundaries. A postmodern work may combine tonal and atonal writing, classical forms and popular rhythms, historical quotations and new sounds, or concert music with theater, film, dance, and visual art.

Common features include:

• quotation and borrowing;

• stylistic collage or pastiche;

• irony and parody;

• renewed use of tonality;

• mixtures of concert, popular, and traditional cultures;

• multimedia and theatrical collaboration.

Examples include Luciano Berio’s Sinfonia, which combines orchestral writing, vocal texts, and quotations from earlier music; Alfred Schnittke’s Concerto Grosso No. 1, which places Baroque gestures, modern dissonance, popular idioms, and theatrical contrasts together; John Adams’s Harmonielehre, which combines minimalist repetition with late-Romantic harmony; and Laurie Anderson’s O Superman, which blends electronic loops, spoken text, performance art, and popular-song structures.

When listening, identify the references and ask how each quotation functions. It may be serious, humorous, nostalgic, critical, or deliberately ambiguous.

Takeaway: Postmodern musical meaning often comes from the relationships among contrasting styles rather than from a single consistent vocabulary.

Film Music as Narrative and Psychology

Film music works together with images, dialogue, sound effects, editing, and narrative. A score can establish a setting, suggest a character’s psychology, create suspense, foreshadow events, shape pacing, or connect separate parts of a film. A leitmotif is a recurring musical idea associated with a character, place, object, or concept.

Source music appears to come from within the film’s world, such as music from a radio or nightclub. Nondiegetic music is heard by the audience but not by the characters. After 1945, film composers combined symphonic traditions with jazz, popular song, electronic sound, world instruments, and studio technology.

Representative examples include:

• Bernard Herrmann’s Psycho uses sharply accented strings to intensify psychological violence and suspense.

• Ennio Morricone’s The Good, the Bad and the Ugly uses unusual timbres, vocal effects, and spacious gestures to reshape the sound of the Western.

• John Williams’s Jaws turns a simple repeating two-note idea into a symbol of approaching danger.

• Williams’s Star Wars revives a large symphonic and leitmotivic approach for blockbuster cinema.

• Vangelis’s Blade Runner uses synthesizers and atmospheric electronic textures to create a futuristic urban sound world.

• Trent Reznor and Atticus Ross’s The Social Network demonstrates how electronic production and popular-music aesthetics can function as dramatic scoring.

A useful comparison is to watch a short scene once with the soundtrack muted and once with it restored. Notice changes in pacing, character sympathy, danger, anticipation, location, historical period, and the sense that an event is realistic, comic, tragic, or surreal.

Takeaway: Film music does not merely accompany images; it helps construct narrative meaning and emotional interpretation.

Jazz after 1945

Postwar jazz developed through overlapping styles rather than one simple sequence. Cool jazz emphasized restrained tone, lighter textures, and controlled phrasing. Hard bop returned to blues, gospel, and stronger rhythmic drive. Modal jazz used scales or modes as extended harmonic fields. Free jazz loosened or abandoned conventional chord changes, fixed forms, and regular meter. Fusion combined jazz improvisation with rock, funk, electronic instruments, and amplified performance.

Jazz is defined not only by compositions but also by performance practice. Listen for improvisation, swing or syncopation, interaction among performers, timbral individuality, and transformation of a melody.

Important examples include:

• Miles Davis’s Kind of Blue is a landmark of modal jazz, with spacious improvisation over relatively stable harmonic areas.

• Ornette Coleman’s Free Jazz uses collective improvisation and an expanded approach to form and harmony.

• John Coltrane’s A Love Supreme combines spiritual purpose, repeated motives, intense improvisation, and large-scale development.

• Herbie Hancock’s Head Hunters connects jazz improvisation with funk grooves, electric instruments, and studio production.

Compare Kind of Blue with Free Jazz. In the first, a listener can often follow a recurring harmonic framework and the succession of solos. In the second, listen for collective density, changing instrumental roles, and the absence of a conventional song-form roadmap.

Takeaway: Postwar jazz continually redefined the balance among composition, improvisation, interaction, technology, and groove.

Popular Music and the Recording Studio

After 1945, popular music became increasingly shaped by recording technology. A recording could be a constructed musical object rather than merely a document of a live performance. Overdubbing, multitrack recording, editing, effects, sampling, and electronically produced sounds allowed producers to shape details that might not be reproducible in a single live event.

Major developments include:

• Rock and roll: A synthesis of rhythm and blues, country, gospel, and blues that became a major youth culture in the 1950s.

• Soul and funk: Styles emphasizing expressive vocals, groove, syncopation, bass lines, and social commentary.

• Disco and electronic dance music: Music organized around continuous beat, repeated grooves, and studio-mediated production.

• Punk and alternative rock: Styles often favoring directness, distortion, short forms, and resistance to commercial or institutional expectations.

• Hip-hop: A cultural and musical practice involving DJing, breakbeats, MCing or rapping, Sampling, scratching, dance, and visual art.

Examples include The Beatles’ Sgt. Pepper’s Lonely Hearts Club Band, Marvin Gaye’s What’s Going On, Kraftwerk’s Trans-Europe Express, Grandmaster Flash and the Furious Five’s “The Message,” and Public Enemy’s It Takes a Nation of Millions to Hold Us Back. These works demonstrate studio experimentation, layered production, electronic rhythm, social commentary, dense sampling, and the album or recording as an artistic statement.

When listening, distinguish between the song and the recording. Ask which sounds could be reproduced live, how the producer shapes the texture, and how repetition creates identity and momentum.

Takeaway: Popular music after 1945 made production, technology, and the recording studio central parts of musical authorship.

Global Traditions and Cultural Exchange

The postwar period intensified the circulation of recordings, instruments, performers, and musical ideas. “Global music” is not one homogeneous genre: every tradition has its own history, social function, performance practice, and cultural vocabulary. Responsible listening therefore connects sound with community, identity, migration, religion, dance, politics, and cultural exchange.

Important areas of study include:

• South Asian classical music: Listen for raga, improvisational development, drone, and rhythmic cycles. International performances by Ravi Shankar helped bring North Indian sitar music to wider audiences while also raising questions about cultural translation and commercialization.

• Indonesian gamelan: Listen for interlocking parts, cyclical organization, layered metallic timbres, and ensemble coordination.

• West African and African diasporic traditions: Listen for call-and-response, polyrhythm, layered percussion, participatory performance, and the relationship between music and dance.

• Afrobeat: Fela Kuti’s music combines West African rhythmic practices, funk, extended grooves, political lyrics, and large-ensemble performance.

• Latin American popular traditions: Salsa, bossa nova, tango, and related styles reflect interactions among African, European, Indigenous, and Caribbean histories.

• Reggae and Jamaican sound-system culture: These emphasize bass, offbeat rhythm, repetition, dub production, and creative reuse of recorded material.

Compare a Western concert work with a recording from a community-based or dance-centered tradition. Consider whether the beat is regular, cyclical, or flexible; whether layers are independent or coordinated; whether improvisation is expected; and whether the audience listens, dances, sings, responds, or participates.

Takeaway: Global exchange can broaden musical possibilities, but meaningful listening requires attention to the distinct histories and social settings of each tradition.

Active Listening Strategies

Contemporary and popular works may not follow a familiar melody-and-harmony structure. A flexible listening process helps reveal how the music works.

1. First hearing: overall impression. Note the mood, energy, instrumentation, apparent setting, and strongest recurring idea.

2. Second hearing: musical materials. Track timbre, texture, register, rhythm, pulse, dynamics, harmony, melody, and production effects.

3. Third hearing: organization. Identify repetition, contrast, gradual process, improvisation, sampling, montage, quotation, or chance.

4. Fourth hearing: cultural meaning. Ask who made the music, for whom, in what setting, and with what technological or social purpose.

A listening chart can organize observations:

• Timbre: What makes the sound recognizable: an instrument, voice, electronics, distortion, or environmental noise?

• Texture: Is the music monophonic, homophonic, polyphonic, layered, sampled, or continuously changing?

• Rhythm: Is there a steady beat, repeating cycle, syncopation, polyrhythm, or free rhythm?

• Form: Does the work use song form, sectional contrast, repetition, gradual process, improvisation, or montage?

• Performance: Are choices fixed by notation, improvised, selected by chance, or shaped in the studio?

• Context: What social, religious, political, technological, or cinematic setting informs the music?

Takeaway: Active listening becomes more precise when it moves from overall impression to sound materials, organization, performance choices, and cultural meaning.
