I think this is a response to my post, but, as I mentioned to GramPon yesterday, I would be grateful if you could quote a line or two because it is really difficult to find the associated post, especially on a long thread. thanks.

What do you personally think makes music a "strong survival trait"?

Is it just base line, strutting peacockery?

Definitely not the latter.
When people were out of sight of one another, they would, having already evolved from species which communicated by sounds, have realised that a series of notes, vocalised in a certain way, greatly aided communication. they would have found out the different ways the voice and language could be used, so adapting that to distances, with whistles etc, would have greatly increased safety.

The sounds of various voices making harmonies would have been of strong group benefit.

What do you think?
