Final answer:
The mixing of two or more cultural traditions in art forms is known as cultural hybridization, where cultural practices blend to form new artistic expressions reflecting a fusion of diverse cultural identities.
Step-by-step explanation:
The mixing of two or more cultural traditions in art forms and practices is referred to as cultural hybridization, syncretism, or convergence. This process demonstrates how cultural practices can blend and create new expressions, often occurring on the periphery, or near the borders of folk regions.
Such interweaving of cultures has historically been evident, for instance, during the European colonization of the Americas. Indigenous traditions mixed with European influences, particularly under Spanish rule where missionaries utilized Indigenous artists to create a new society's art forms. The resulting artwork often reflected a fusion of the two distinct cultural identities, combining local materials and iconography with European techniques and forms.
The Catholic Church played a significant role in the cultural integration of artistic expressions in places like Mexico, where biblical stories and church traditions influenced a new national artistic identity.
Furthermore, around the world, theatrical and performative traditions, such as the Chinese Opera, Indian dance dramas, Japanese Kabuki, and others have evolved from the interwoven cultural journeys of their respective regions. Each form adapts specific conventions and reflects the cultural values and aesthetics that have shaped them, indicating a rich history of cultural interchange in the arts.
