The history of twelve-tone music is inextricably linked with the development of atonality in the early 20th century. The first compositional use of the twelve-tone technique was by Austrian composer Arnold Schoenberg in his Second Quartet (1908). Schoenberg's pupils Alban Berg and Anton Webern were also early adopters of the technique. Twelve-tone music was developed further by a number of composers associated with the "Second Viennese School", including Josef Matthias Hauer, who independently discovered and developed his own version of the technique (known as "Hauer's tone rows").      Visit https://www.twelvetonemusicschool.com/
