Anton Webern was an Austrian composer and conductor, born in 1883 and known for his significant contributions to 20th-century music. He was a key figure in the Second Viennese School, alongside Arnold Schoenberg and Alban Berg. Webern's music is characterized by its brevity, clarity, and use of twelve-tone techniques, which he helped to develop. Webern's works often feature sparse textures and innovative orchestration, making them distinct within the modern classical repertoire. His compositions, such as Symphony, Op. 21 and Five Pieces for Orchestra, reflect his interest in exploring new musical forms and ideas. He passed away in 1945, leaving a lasting impact on contemporary music.
