Edited by Ron Erickson. Sonata No.4, completed in 1948, was entitled 'No. 2' by Antheil. It appears, from the list of workds he made in 1944, that of the works from the Paris years he wanted to consolidate the Sonata No. 1 with the third and ignore the second, so that all the violin and piano sonatas before 1940 would be known as one work - called Sonata No. 1.
Modern notation conventions have been adapted to Antheil's chromatic-polytonal language in order to make the text as definite and as readable as possible. In this edition, poytonal key signatures sometimes are substituted for masses of accidentals.
