What developments led to serialism?

Serialism emerged in the early 20th century as a response to the perceived limitations of traditional tonal music. Key developments included the exploration of atonality by composers like Arnold Schoenberg, who sought a new compositional approach that moved beyond conventional harmonic structures. The establishment of the twelve-tone technique further formalized this idea, using a series of all twelve pitches as the basis for musical organization. This shift was also influenced by broader cultural movements that embraced innovation and abstraction in art and literature.
