______ textures, produced by many rhythms going on at the same time, are distinctive of African music.

Polyrhythmic textures are key characteristics of African music, involving the use of multiple independent rhythms occurring simultaneously. This creates a complex and interwoven rhythmic structure that adds depth and richness to music. African musical traditions often emphasize these layered rhythmic patterns, generating a vibrant and dynamic sound.

The significance of polyrhythms lies not only in their technical complexity but also in their role in the cultural expression and social functions of the music, where community participation and intricate timing are essential elements. This contrasts with other musical textures that may focus more on melody or harmony without the same level of rhythmic interplay. Hence, polyrhythmic textures embody the essence of African music's rhythmic vitality, making this answer the most fitting choice.
