Symphonia

In Greek, symphonia literally translates to "agreement," but the word has been used to refer to a number of different concepts. It has been the term for many instruments in Ancient Greece, including bagpipes, a drum, and the clavichord. In Eastern Orthodox theology, Symphonia is the idea that the church and state should exist in harmony and neither should dominate.

Symphonia would certainly work as a baby name, especially as elaborate Greek names such as Persephone and Ophelia rise in use.

Pronounced sim-FO-nee-uh.
