What is Serialism?

Serialism is a method of musical composition that organizes musical elements using a predetermined series or sequence. It became prominent in the early 20th century as composers looked for new ways to structure music beyond traditional tonal harmony. Serialism most commonly refers to the use of ordered pitch sequences, often called tone rows, that determine the notes used in a composition.

In the most well-known form of serialism, known as twelve-tone technique, all twelve notes of the chromatic scale are arranged into a specific sequence. This sequence must be used before any note is repeated, ensuring that no single pitch becomes the tonal center. The tone row can also appear in different variations, such as being reversed, inverted, or played backwards.

Serialism was developed and popularized by composers such as Arnold Schoenberg, along with his students Alban Berg and Anton Webern. Their work greatly influenced 20th-century classical music by introducing highly structured approaches to composition. Serial techniques were later expanded to organize other musical elements such as rhythm, dynamics, and articulation.
