This is a Song that Jacqli made during Ar tonelico II: Melody of Metafalica to converse with the Heart of the Land that was hidden in the deepest reaches of Gaea. Technically speaking, it's a high-level kind of Hymmnos because of each line being improvised by Jacqli whenever the Heart replies to her feelings or whenever she expresses her feelings, something that not many Reyvateils would be capable of doing. Particularly important is the fact that this Song is created from the synchronization established between the Reyvateil and the Heart of the Land once the Heart has started singing, but this only happens if both sides are willing to at least talk to each other: if they do, they will make a Song like this one, but otherwise it will end in failure. Additionally, this Song isn't a Hymmnos
