Jeez Louise, I thought I'd scheduled this post to appear tuesday. Maybe a bug with the CMS, no clue honestly. Sorry :U
(It was up on Patreon last week, at least!)
I don't have any cool music or anything to share, but I do have this article on sperm whale communication. When I was first planning Sennan out, I had to make an executive conlang decision about what the nature of the language would be, and I decided on "human-like". It was convenient that the Esani are technically amphibious, so their language would have to work in and out of the water, but I always imagined that it would sound very different spoken through air vs water. I also imagined that "voiced" and "unvoiced" consonants would have a much different quality to them, depending, and that something like a "t" would probably sound more click-like than the way a human would pronounce a "t".
But this is all really just a roundabout way of saying "I needed something easy for me and familiar enough for the reader". Laziness saves the day!
