Johannes Brahms s organ works in a sense frame his whole oeuvre. He wrote several preludes and fugues and the chorale prelude O Traurigkeit o Herzeleid in the mid-1850s at a time when he was making an intensive study ofcounterpoint. The Eleven Chorale Preludes op. 122 on the other hand are Brahms s final work composed in 1896 immediately before and after the death of Clara Schumann. This revised Henle Urtext edition presents all of Brahms sorgan works in a single volume following the musical text of the New Brahms Complete Edition and with a preface and a commentary that reflect the latest scholarship. The early versions of two of these pieces are also given in anappendix.
