Klavierbüchlein für Wilhelm Friedemann Bach

Most of the pieces included are better known as parts of The Well-Tempered Clavier and the Inventions and Sinfonias.

The authorship of most other works is debated: particularly the famous Little Preludes BWV 924–932 are sometimes attributed to Wilhelm Friedemann Bach.

The book begins with a preface that contains an explanation of clefs and a guide to playing ornaments.

They were probably added by Johann Caspar Vogler, Bach's pupil and successor at Weimar.
