Among Bach's lesser known keyboard works are seven toccatas (BWV 910–916), four duets (BWV 802–805), sonatas for keyboard (BWV 963–967), the Six Little Preludes (BWV 933–938), and the Aria variata alla maniera italiana (BWV 989). Bach exploited the capabilities of an instrument to the fullest while keeping the core of such music independent of the instrument on which it is performed. As such, after some delay, he was able to induce his friends at court to hold an official inquiry, and his dispute with Ernesti was settled in 1738. ", Leopold, Prince of Anhalt-Köthen, hired Bach to serve as his Kapellmeister (director of music) in 1717.

Many of Bach's works during the 1730s and 1740s were written for and performed by the Collegium Musicum; among these were parts of his Clavier-Übung (Keyboard Practice) and many of his violin and keyboard concertos.. 71, Gott ist mein König (God Is My King), of February 4, 1708, was printed at the expense of the city council and was the first of Bach’s compositions to be published.

He presented the manuscript to the Elector in an eventually successful bid to persuade the prince to give him the title of Court Composer. The principles of four-part harmony are found not only in Bach's four-part choral music: he also prescribes it for instance for the figured bass accompaniment.
