Sound Horizon Concepts
Many words in Sound Horizon lyrics symbolize greater concepts, and tracking them across Revo's works can amount to a difficult task. This page chronicles and categorizes them, in addition to their appearances in Revo's other works to help illuminate their meaning. They are rendered in their romaji form (excepting those usually spoken or sung in another language i.e. English or French) to assist general readability and to account for Japanese words corresponding to multiple English phrasings depending on context.
