Very excited for Elsweyr, since I main khajiit. So I kept thinking about it, and idea just happened.
What if Khajiit use their tails when they play music?
Naturally, the harp is moon-based. Though I decided that Sun-and-Moon theme will create more interesting shape.
Sun's 'rays' have jingle bells suspended in them, so musician hits them with the tail, while plucking strings with fingers.
Sketches are loose, but it mostly to conceptualize the idea. I will develop it later.
I imagine it sound something like this, only music itself more of khajiiti flavor.
