Musical languages are languages based on musical sounds rather than articulation. They can be categorized as constructed languages, and as whistled languages. The latter are dependent on an underlying articulatory language, in actual use in various cultures as a means for communication over distance, or as secret codes. The mystical concept of a language of the birds connects the two categories, since some authors of musical a priori languages speculated about a mystical or primeval origin of the whistled languages.
