Answer: D

Explanation:

Sonata form was developed in the eighteenth century.

Sonata form, a significant structure in classical music, particularly in the first movements of symphonies by composers like Haydn and Mozart, originated in the eighteenth century.

A) fifteenth century

This option is incorrect as sonata form was not developed during the fifteenth century. The musical forms prevalent at that time were primarily based on medieval and early Renaissance styles, which did not include the structured complexity of sonata form.

B) sixteenth century

While the sixteenth century saw the development of various musical forms, sonata form specifically did not emerge until later. This period was more focused on the maturation of polyphony and the madrigal, rather than the homophonic textures that characterize sonata form.

C) seventeenth century

The seventeenth century was a time of experimentation in music, leading to the Baroque style, but sonata form itself did not take shape until the following century. The developments in instrumental music during this time laid groundwork but did not culminate in sonata form.

D) eighteenth century

This option is correct as the eighteenth century marks the true emergence and establishment of sonata form, particularly through the works of composers like Haydn and Mozart. It became a foundational structure for the Classical period, defining the way symphonic and sonata compositions were structured.

E) nineteenth century

This option is incorrect because, although the nineteenth century saw further evolution and expansion of sonata form, it was not the period in which the form was developed. By this time, sonata form was already an established practice in classical music.

Conclusion

The correct answer is definitively D) eighteenth century, as this is when sonata form was established as a fundamental structure in classical music, particularly exemplified by the works of Haydn and Mozart. The other options fail to accurately represent the historical development of this significant musical form.
