I want to know the answer to the following question:
What publication of Jean-Jacques Rousseau was a leading text in the late 18th century and was published 1767 in Geneva and 1768 in Paris?
All the background I'm provided with is that "From the Earliest Ages to the Present Period (1776), which was a historical survey and an attempt to rationalize elements in music systematically over time.". Is that enough to answer the question?
Answer: no
