PS The article cited as the source for arguments about Romance is questionable First it is an online article and not a published peerreviewed article so its authority can be questioned Second that article cites sources that are even more questionable such as emails from Ophee a trained pilot  publisher not a peerreviewed musicological publication or dating done by means of scientific methods by experts Third you cannot cite a pdf image of a photocopy of a socalled earlier or original text Fourth upon what evidence does Ricordi base its attribution of the piece to Rubira What is the socalled evidence that Rubira wrote the piece in the th century If there is anything concrete CITE it Cite original verifiable texts that make the arguments not your buddys little internet article which no real academicscholar would accept as being proof of anything  Finally lets have some proof that this Antonio Rubira character even existed in reality I may be wrong on this last point but something about it smells fishy and contrived so a publisher can make money
