“旋宫”、“转调”(“犯调”)是两个概念;“顺旋”、“逆旋”是两种方法;“之调”、“为调”是两种称谓。“宫”不能离开“调”,“调”不能缺少“宫”。“宫音”和“调声”之间所具有的相互依存、相互制约的关系是“宫调”理论形成和存在的基础。“夫宫,音之主也”,“宫”为“上”,“调”为“下”,二者为两个层次,并非“两个系统”。 “Rotary” and “transfer” (“transfer”) are two concepts; “smooth spin”, “reverse spin” are two methods; “tone”, “tone” are two titles. “Palace” can not leave “tone”, “tone” can not be missing “palace.” The interdependence and mutual restraint relations between “Gong Yin” and “Tune Sound” are the basis for the formation and existence of the “Gong Tune” theory. “Fu Gong, the Lord of tone”, “Palace” is “on”, “tune” is “under”, both at two levels, not “two systems.”
