Aria draws on the Italian musical term for a solo melody, with a secondary thread linking it to a Persian word for "air" or "noble." Both readings point toward something expressive and lifted -- a voice rising above the rest. The name is often understood as carrying artistry and lightness rather than solemnity.
When a Planet who is a Fortune is in Conjunction with an Infortune, he allays his malice, so that the Infortune shall do no hurt. - William Lilly (1602.-1681.)
