I have just come back from holiday in New Zealand. Spent some time walking in (what remains of) the native bush, where the dominant species were always birds - with a phenomenal variety of calls, at all times of the day.

For the Maori before the Europeans arrived and exterminated most of the birdlife, the sound would have been overpowering. The whole country was a vast birdsong choir. Maori instruments were limited in variety and mostly quiet.

Taonga Puoro

There can have been no such thing as solo music - whatever you played, you were playing along with the birds, and the vast superiority of their acoustic resources to anything a human could do would have been obvious. Playing an instrument would have been a statement of humility.
