Final answer:
The origin of popular music notably involves its folk roots and cultural hearths, while its diffusion embodies the spread and adaptation to different locales. Hip hop's evolution from the Bronx to global influence is a prime example of these processes, demonstrating patterns like stimulus diffusion. Factors impacting the spread include social, economic, and technological barriers and developments.
Step-by-step explanation:
Elements of the Origin and Diffusion of Popular Music:
The elements of the origin and diffusion of popular music can be traced to its folk origins, transformation into pop culture, and evolution through adaptations like stimulus diffusion. The birthplace of a genre, often referred to as the cultural hearth, has significant influence, as we saw with hip hop originating in the Bronx before diffusing globally.
The driving forces behind the diffusion of music genres, such as hip hop, can be economic, social or technological advancements like the press or the internet. Hip hop's journey from a localized Bronx scene to worldwide recognition illustrates these patterns of diffusion over time and barriers such as social and economic conditions. The alteration and adaptation of hip hop in different regions, exemplified by New Jersey artists producing Rapper's Delight, and the emergence of gangsta rap in Los Angeles, highlight the concept of stimulus diffusion where core elements spread but also morph according to local influences.
