Final answer:
Jazz is the music style that depended on the diaspora, as it evolved from the African American communities and was influenced by the cultural blend resulting from migration. Unlike jazz, Baroque, Gregorian chant, and Classical music were not directly influenced by diaspora but were developed within specific historical and regional contexts.
Step-by-step explanation:
The style of music that depended on diaspora is jazz. Jazz is a genre deeply rooted in the experiences and culture of the African diaspora. The movement of African people due to slavery and later migration contributed to the blend of cultural influences that characterized jazz. Its development was heavily influenced by the African American communities, especially in the Harlem Renaissance era, signifying a rich cultural exchange and incorporation of diverse musical styles, including blues.
On the other hand, genres like Baroque, Gregorian chant, and Classical music, although influenced by various historical and cultural factors, were not a direct result of diasporic movements. Baroque music thrived in Europe during the 17th and 18th centuries, with composers like Bach and Handel. Gregorian chant, a sacred form of music, was developed within the Western Christian Church and Classical music evolved later, shaped greatly by composers like Mozart and Beethoven, reflecting the European traditions of music.
