But I don't think there is a stringed instrument of this size. It's bigger than a violin and smaller than a cello. Well, it may be a viola, but considering that most of the classical musicians deride violas I doubt Octavia would play the viola :v
It would be too small to exist if it would be smaller than a violin. And it isn't. It's to small for a cello and too big for a violin. And maybe for a viola too, but I don't think I've ever seen one so I'm not sure. Aaand it's sad I had to use urban dictionary for your comment (and I still don't really understand what you mean by this sentence (why would you, english-speaking folks, use a complicated name of a show as a word?)).
I'm nor angry or anything actually, it's just how I'm writing. I usually write text walls, long sentences and stuff :c Well, that explains a lot ^^ (I mean, that sounds-like-chinese-for-me term) And generally I just like to, ee... (Well, having a polish-english urban dictionary would be nice...) Generally I just like... ...Clinging to details..? :/ I just like it, however it is called.
