Answer:
Syncretism
Step-by-step explanation:
Syncretism:
It can be defined as the fusion of a variety of practices, philosophies, cultures and beliefs, which involves merging of practices of diverse classes of thought, thus stating a fundamental solidarity and taking into account a comprehensive way to deal with different beliefs.
An instance of the Syncretism is that of Halloween which includes the touch of both the Pagans and the Christian.
Thus the Contemporary Australian aborigine band preserving their instruments and traditional songs is an example of Syncretism.
