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.
