These pieces from the Little Clavier Book for Wilhelm Friedemann Bach belong to the Baroque period.
This little music instruction book was begun on January 22, 1720 by Johann Sebastian Bach for his eldest son, Wilhelm Friedemann, who was then about nine years old.
The Clavier-Büchlein was also probably used for the musical instruction of Bach's younger children, including Carl Philipp Emanuel and Johann Christian.
The Clavier-Büchlein vor Wilhelm Friedemann Bach [Little Clavier Book for Wilhelm Friedemann Bach] is in fact a collection of pieces suitable for any keyboard instrument.
