Atonality is music that avoids a tonal centre — no key, no 'home' chord. Developed by Arnold Schoenberg in the early 20th century, it became the foundation of much 20th-century classical music and remains controversial and fascinating.
Atonal music is music that deliberately avoids establishing a tonal centre — there is no 'home' key, no primary chord the music gravitates toward or resolves to. All twelve notes of the chromatic scale are treated as equally important, rather than the hierarchical relationships (tonic, dominant, subdominant) that define tonal music. Atonality developed gradually as composers in the late 19th century (Wagner, Liszt) pushed chromaticism to its extreme limits, dissolving the sense of key. Arnold Schoenberg is the central figure in the development of atonality — his free atonal works from 1908 onward (Pierrot lunaire, Three Piano Pieces Op.11) abandoned key signatures entirely. He later systematized atonality into the twelve-tone (serial) technique: a method of composing using a fixed row of all 12 chromatic pitches in a set order, ensuring no pitch is repeated before all others have been used, thus preventing any one pitch from functioning as a tonal centre. Atonal music sounds dissonant and unfamiliar to listeners trained on tonal music — the resolution patterns the ear expects never arrive. Understanding atonality requires both theoretical study and repeated listening. It is an important part of 20th-century music history and conservatory education, even for musicians who ultimately work in tonal styles.
Virgoul composition and music theory teachers can guide you through 20th-century harmonic developments — from late Romanticism through atonality, serialism, and beyond — in relation to the music you want to understand and create.
Join VirgoulBecause the ear, trained on tonal music, expects certain harmonic patterns — tension followed by resolution to a home chord. Atonal music deliberately avoids providing those resolutions, so the ear never gets the expected harmonic 'payoff.' This is disorienting rather than aesthetically flawed — it is an intentional rejection of the conventions of tonal music. With repeated listening, many listeners develop the ability to follow atonal music on its own terms.
Twelve-tone (serial or dodecaphonic) music is a compositional technique developed by Arnold Schoenberg in the 1920s. The composer creates a tone row — a specific ordering of all 12 chromatic pitches. This row and its transformations (inversion, retrograde, retrograde inversion) form the pitch material of the entire piece. The technique ensures no single pitch becomes a tonal centre. Major twelve-tone composers: Schoenberg, Webern, Berg, Dallapiccola, Boulez, and Nono.
Generally no — jazz is tonal, built on chord progressions with clear functional harmony. However, free jazz (Ornette Coleman, Cecil Taylor, Albert Ayler) from the late 1950s onward deliberately abandoned fixed chord changes and conventional tonality, producing music that overlaps with atonal aesthetics. The term 'free jazz' reflects this liberation from tonal structures, though it is philosophically distinct from Schoenbergian serialism.
