Music

, a style of blues music that originated there in the late 19th century. According to the Piedmont Blues Preservation Society, most Piedmont blues musicians came from Virginia, North and South Carolina, and Georgia. During the Great Migration, African Americans migrated to the Piedmont. With the Appalachian Mountains to the west, those who might otherwise have spread into rural areas stayed in cities and were thus exposed to a broader mixture of music than those in, for example, the rural Mississippi delta. Thus, Piedmont blues was influenced by many types of music such as
ragtime Ragtime, also spelled rag-time or rag time, is a musical style that flourished from the 1890s to 1910s. Its cardinal trait is its syncopated or "ragged" rhythm. Ragtime was popularized during the early 20th century by composers such as Scott ...

Cities

Many major cities are located on the Atlantic Seaboard fall line, the eastern boundary of the Piedmont. (In Georgia and Alabama, where the Piedmont runs mostly east to west, the fall line is its southern boundary.) The fall line, where the land rises abruptly from the coastal plain, marks the limit of navigability on many major rivers, so inland ports sprang up along it. Within the Piedmont region itself, there are several areas of urban concentration, the largest being the
