It seems like 70% of all bands have a song about the music business. Either about songs, or touring, or being in a band.
And there are plenty of novels about writing novels, or about being an author. Murder mysteries about someone killing the writers of murder mysteries, even!
There are poems about poems. There are probably even poems that are about poems about poems, but I can't be arsed to go looking.
Is there a term for this, either in general or more specifically? That is, do we have a term for "reflexive art"? Or is there a specific term for Limericks about Limericks or books about writing or songs about music?
Note that I'm not focused solely on "arts." There are certainly computers used for designing computers, and "AI" is supposed to put all the programmers out of work any day now. There is even architecture about architecture! (All the buildings are insulated with foam, ignore the real-world properties of materials, and take an extra year to build.) But I'm inclined to believe that if such a word exists, it probably exists in one of the word-oriented fields, first.
