"Lenguajes artísticos y comunicacionales" is the name of a subject on an Argentine secondary school transcript.

I have found the fundamentals of the subject (description of what it is about) in http://contenidosdigitales.ulp.edu.ar/exe/lenguaje-artistico...

"Artistic and communicational languages" is too literary, and I would say inadequate; on the one hand, wouldn't "communicational language" be a redundancy?
On the other hand, "artistic language" is something different: "An artistic language (commonly called artlang[1][2][3]) is a constructed language designed for aesthetic pleasure. Unlike engineered languages or auxiliary languages, artistic languages usually have irregular grammar systems, much like natural languages. Many are designed within the context of fictional worlds, such as J. R. R. Tolkien's Middle-earth. Others represent fictional minority languages in a world not patently different from the real world, or have no particular fictional background attached."

Pensé en "Communication through languages and art", pero no es exactamente lo que dice en inglés tampoco.

¿Alguien a quien se le ocurra alguna alternativa teniendo en cuenta este contexto?

¡Desde ya muchas gracias!
