Which composer developed the twelve-tone technique and experimented with atonal music?

• A. Ludwig van Beethoven
• B. Arnold Schoenberg
• C. Johann Sebastian Bach
• D. Igor Stravinsky

Answer: (B)

The main idea here is the creation of a systematic way to organize all twelve chromatic pitches so no single note remains the tonal center. Arnold Schoenberg developed the twelve-tone technique, also called dodecaphony, in the early 20th century as a path beyond traditional major/minor harmony. The technique revolves around a tone row: a specific order of all twelve pitches used as the source material. From that row, composers derive musical material through transformations such as transposition (shifting the row up or down), inversion (turning the interval directions upside down), retrograde (playing the row backward), and retrograde-inversion. This approach keeps the music from centering on any key, creating an atonal texture that is governed by the row and its transformations rather than by conventional tonal priorities. Schoenberg also pushed into atonality even before the twelve-tone system was fully codified, and his later work helped establish serialism as a new direction for modern music. This method influenced many composers after him and became a guiding principle for postwar experimental music. The other composers listed belong to earlier or different approaches: Bach and Beethoven are rooted in tonal traditions, while Stravinsky explored many styles but did not originate the twelve-tone technique.
