Symphonic Power

Symphonic Power, also incosistently translated as Power Energy in Ar tonelico II: Melody of Metafalica, is the official name for the energy used in Ar Ciel for powering up every kind of machine, and to the energy that allows the manifestation of Song Magic in the physical plane.

Strictly speaking, the Symphonic Power is no more than a concentration of Dynamic D-Waves, and their flow is what allows to use it as energy for all kinds of appliances, from the most simple of machines, to the entirety of the First Tower of Ar tonelico.

The main way in which this energy is produced is through the conversion made through Songstones, or from their subcomponents, Grathnode and Parameno, which allows to transform sounds into energy.
