Means “song, melody” in Italian (literally means “air”). An aria is an elaborate vocal solo, the type usually performed in operas. As an English name, it has only been in use since the 20th century. It is not common in Italy.
From the Greek Ἄργος (Argos), derived from ἀργός (argos) meaning “glistening, shining”. This name was borne by several characters from Greek myth, including the man who built the Argo and a giant with one hundred eyes.
