In the second half of the 1720s, Bach had already written versions of all three movements of the concerto for two of his cantatas with obbligato organ as solo instrument: the first two movements for the sinfonia and first choral movement of "Wir müssen durch viel Trübsal in das Reich Gottes eingehen, BWV 146" (1726); and the last movement for the opening sinfonia of "Ich habe meine Zuversicht, BWV 188" (1728). In these cantata versions the orchestra was expanded by the addition of oboes.
