Composer's unfinished finale to opera for Hindu god (6)
I believe the answer is:
brahma
'hindu god' is the definition.
(Brahma is an example)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for brahma that I've seen before include "Hindu creator god" , "being worshipped" , "god to many Indians" , "Heavy domestic fowl with feathered legs and feet" .)
