Which style of music evolved into African Jazz and originated in South Africa during the 1930s-1960s?

The style of music that evolved into African Jazz and originated in South Africa during the 1930s-1960s is Marabi. This genre emerged in urban areas, particularly in the black townships, and is characterized by its use of repetitive melodic patterns and the incorporation of various musical influences, including American jazz.

Marabi served as a precursor to African Jazz and played a significant role in the development of the music scene in South Africa. The unique rhythms and styles of Marabi captured the social and cultural experiences of the people during that time, blending local musical traditions with jazz elements. This evolution was crucial in shaping South Africa's musical identity and led to the emergence of new jazz forms that incorporated indigenous sounds and styles, ultimately influencing the broader landscape of African music.

The other musical styles mentioned have their own distinct characteristics and origins that do not directly lead to the development of African Jazz in the same way Marabi does.
