The Symphony No. 4 in D minor, Op. 120, composed by Robert Schumann, was first completed in 1841. Schumann heavily revised the symphony in 1851, and it was this version that reached publication.
Clara Schumann, Robert's widow, later claimed on the first page of the score to the symphony—as published in 1882 as part of her husband's complete works (Robert Schumanns Werke, Herausgegeben von Clara Schumann, published by Breitkopf & Härtel)—that the symphony had merely been sketched in 1841 but was only fully orchestrated ("vollständig instrumentiert") in 1851. However, this was untrue, and Johannes Brahms, who greatly preferred the earlier version of the symphony, published that version in 1891 despite Clara's strenuous objections.
