Mechanical instruments such as the [[music box]] and [[musical clock]] were popular at the Prussian court, and C. P. E. Bach wrote thirty original compositions for these instruments, grouped together as Wq. 193.{{sfn|''Complete Works''|loc="Cramer and Sturm Songs", ser. VI, v. 2., p. xxiii}}<ref>Shepherd, John.
