Everything is a language. Don’t know how to dance? That just means that you don’t know that language. Don’t know how to appreciate weird music? That means you just don’t know how to read in that language.

Everything is a language to our brain because a language is just a dictionary – an association of feelings/concepts/notions/ideas/mental image/eidetic imagery/mood (x) which are some embedding in the brain’s neural net, to words (y). x is to y.

If y = playing piano, then it means you can translate from x to piano music. You can speak piano. And if you can “appreciate” piano music, then you can read piano, i.e translate from piano music to x (series of feelings/concepts/notions/ideas/mood).

Neural networks simply form associations between two things from the input layer to the output layer. A translator from one domain to another is just an encoder-decoder.
