An integral part of the avant-garde movement in 1920s Paris, the American composer George Antheil collaborated with writers Ezra Pound and James Joyce, violinist Olga Rudge, and befriended the likes of Pablo Picasso, Man Ray, and many others. In Paris, Antheil found great success as the provocateur of riots and scandal at his concerts, with a purposefully controversial compositional style. This document explores, in detail, his three violin sonatas composed between 1923 and 1924 at the behest of Ezra Pound for his violinist friend Rudge. The violin sonatas provide a fascinating perspective on Antheil's musical and personal life during his first years in Paris. The historical and personal contexts of the sonatas are examined, in addition to their musical repercussions for Antheil's compositional style. This document relies primarily on unpublished letters, writings and other memorabilia from collections held at The Library of Congress, New York Public Library, Columbia University, Princeton University, Yale University, and Indiana University. Antheil's published scores and autobiography, Linda Whitesitt's biography of Antheil and other literature pertaining to the period and person are also consulted. While a fair amount has been written on Antheil's more famous work Ballet Mécanique, which stylistically followed the violin sonatas, the lesser-known sonatas have received minimal attention or exploration. This document places these three works into their rightful context, as cornerstones of Antheil's musical style during his most avant-garde years in Paris.
