After Bach completed the Gellert Songs in 1758, he returned to the types of music he had been producing before the war—chiefly solo keyboard works, presumably because of a diminished need for concertos and other ensemble music. He would publish two major ensemble works during the war, the E-Minor Sinfonia and the E-Major Concerto, as well as the Oden of 1762, containing twenty songs, but only a few of the latter were new. He composed almost nothing new in 1761, but by then he must have been busy with volume 2 of the Versuch, which had been advertised in spring 1760 but was not published until probably late in the following year. In addition to updating existing compositions for publication, he seems also to have revised others that remained in manuscript, presumably for sale in that form or for eventual concert use. He may also have been anticipating, not without anxiety, the resumption of court life that would follow the end of the war. If so, he might have been glad, when the war did end and the king returned, that Frederick had diminished enthusiasm for music. The private royal concerts resumed, and with them Bach's commutes to Potsdam, which he dreaded because travel on the rough roads exacerbated his gout.
