some sketches and studies for it which are sure to find high favour as something quite new." The pedalflügel base on which the piano was placed had 29 keys connected to 29 separate hammers and strings encased at the rear of the piano. The pedal board was manufactured by the same Leipzig firm of Louis Schöne that had provided the grand pedal piano in 1843 for the use of students at the Leipzig Conservatory. Before composing any of his own fugues and canons for organ and pedal piano, Schumann had made a careful study of Bach's organ works, of which he had an extensive collection. Clara Schumann's Bach book, an anthology of organ works by Bach, now in the archives of the Riemenschneider Bach Institute, contains the whole of Clavier-Übung III, with detailed analytic markings by Robert Schumann. On the centenary of Bach's death in 1850, Schumann, Becker, Hauptmann and Otto Jahn founded the Bach Gesellschaft, an institution dedicated to publishing, without any editorial additions, the complete works of Bach through the publishers Breitkopf and Härtel. The project was completed in 1900. The third volume, devoted to keyboard works, contained the Inventions and Sinfonias and the four parts of the Clavier-Übung. It was published in 1853, with Becker as editor. At the end of September 1853, having been recommended by the violinist and composer Joseph Joachim, the twenty-year-old Johannes Brahms appeared on the doorstep of the Schumann's home in Düsseldorf, staying with them until early November. Like Schumann, perhaps even more so, Brahms was deeply influenced by Bach's music. Shortly after his arrival he gave a performance on the piano of Bach's organ toccata in F BWV 540/1 in the house of Joseph Euler, a friend of Schumann. Three months after Brahms' visit, Schumann's mental state deteriorated: after a suicide attempt, Schumann committed himself to the sanitorium in Endenich near Bonn, where, after several visits from Brahms, he died in 1856. From its inception, Brahms subscribed to the Bach-Gesellschaft, of which he became an editor in 1881. An organist himself and a scholar of early and baroque music, he carefully annotated and analysed his copies of the organ works; he made a separate study of Bach's use of parallel fifths and octaves in his organ counterpoint. Brahms' Bach collection is now preserved in the Gesellschaft der Musikfreunde in Vienna, of which he became musical director and conductor in 1872. In
