[At the time of Bach it was a frequent usage to omit an accidental from the signature; in the above case the omission of the only flat undoubtedly suggested the appellation frequently given "_in modo dorico_," although otherwise the composition bears hardly a trace of the Dorian mode. Tr.]] III After resigning his post at the palace in Weimar, Bach never again occupied an official position as organist. Not that he renounced the instrument which he so loved to play, but he was no longer obliged to fulfil the requirements of regular service; his earlier compositions he could gather together and correct at his ease, and finally bring out no new ones that were not thoroughly in accordance with his ideals. The number of these new organ compositions also diminished in an extraordinary degree; for from all the thirty-three years embraced in this last period, but about twenty works exist for our study. Although Bach no longer bore the title of organist while at Cöthen, it must not be inferred that access to the organs of the town was denied him; for instance, to the instrument in the _St. Agnuskirche_, the pedal of which was unusually extended in compass. We learn, in fact, from a work of C.F. Hartmann's,[102] published at the beginning of this century, that the pedal of this organ was two and a half octaves in range, extending up to _f'_[sharp][103] inclusive, while the organs of that period usually possessed but two octaves in the pedal, from _C_ to _c'_, with sometimes _c'_[sharp] and _d'_ in addition. [Footnote 102: _Geschichte der evangelisch-lutherischen St. Agnuskirche in Köthen. Herausgegeben von C.F. Hartmann, Köthen, in der Commission der Huschen Buchhandlung_ (1802). The organ is described on pages 19 and 20.] [Footnote 103: [The pedal, even of modern organs, extends upwards only to _f'_. Since the middle of the last decade, the house of Cavaillé-Coll in Paris, has applied to the larger instruments constructed by it the compass of _C_ to _g'_. This range was recommended by the translator and adopted for an organ now in process of construction in Boston; it is also a feature of the large organ for Yale University, recently contracted for.]]
