"A non-literal language, without fixed syntax, and differs from constructed languages that can be used for communication. It focuses entirely on the sounds of language; lacking grammar, meaning, and even distinct words. Instead, it consists of emotive non-lexical vocables and phonemes; in effect, Vonlenska uses the melodic and rhythmic elements of singing without the conceptual content of language."
