20th Century Movements

Emerging in the early 1960s and reaching its peak in the 1970s, Minimalism is defined by repetitive structures, steady pulse, and gradual processual change. The movement reshaped contemporary composition through pared‑down textures and an emphasis on perception.

The twelve‑tone technique era (c. 1921–1960) marks the period when serial organization of the chromatic scale became a dominant compositional method in Western art music, spearheaded by Arnold Schoenberg and his pupils.

Expressionism in music, flourishing roughly between 1905 and the early 1930s, is defined by extreme emotional intensity, atonal harmony, and innovative timbral experiments.

Neoclassicism in music (c.1910–1950) was a 20th‑century movement that looked back to the clarity, balance and formal restraint of the 18th‑century Classical style while employing modern harmonic language and orchestration.

Serialism, emerging in the early 1920s and flourishing through the mid‑20th century, is defined by the systematic organization of musical parameters—most famously pitch—using ordered series. The era reshaped compositional practice with twelve‑tone rows and total serialization.

The Second Viennese School refers to the early‑20th‑century circle of composers centered on Arnold Schoenberg and his pupils Alban Berg and Anton Webern, active roughly from 1908 to the mid‑1930s. It is defined by the systematic abandonment of tonal harmony in favor of atonality and the twelve‑tone method.

Impressionism in music, flourishing roughly between 1880 and 1920, is defined by innovative orchestration, ambiguous tonality, and a focus on atmosphere over formal development.
