Where and when was common-practice tonality developed and codified?

• A. In Africa during the Middle Ages, codified in 1650.
• B. In Europe during the Renaissance, codified in 1600.
• C. In Europe during the Middle Ages, codified in 1700.
• D. In Europe during the Middle Ages and codified in 1750.

Answer: (D)

The main idea being tested is when and where the system of common-practice tonality became established and described. In Western music, tonal organization—centered on major and minor keys, functional harmony, and predictable voice-leading—developed in Europe and gradually formed into a standard approach during the Baroque through the Classical periods. The formal description and a widely taught framework for how this harmony works were codified in Europe in the 18th century, with important theoretical works around the 1730s to 1750s that solidified the rules musicians would follow for generations. That’s why locating it in Europe and around 1750 best fits the idea being tested. Options that place the development in Africa or during the Middle Ages don’t align with how and when this tonal system actually came together, and a date like 1600 or 1700 doesn’t capture the period when the theory was most systematically articulated.
