摘要：以七声配十二律, 可得十二宫、 七十二调, 合称八十四宫调, 其中未有 "仙吕入双角 (调)" 之名. 隋唐以来的实际音乐实践中, 十二宫并未全用, 最多只用七宫. 然而, 戏曲曲谱常以 "九宫" 命名, 编纂体例也以九宫为线索统辖曲牌. 实际上, "九宫" 之名虽属燕乐宫调之范畴, 但在明清之理论典籍以及南北曲谱中已没有了调高的理论意识, "仙吕入双角 (调)" 也只是曲牌组合而已, 并无他意, 两者皆有名无实. 此外, 笛上七调顺序, 常有 "高不过五, 下不过乙" 之称, 而 《碎金词谱》 "凡例" 中所称 "下不过上, 上不过乙", 乃音阶之顺序排列.%To match seven notes with twelve temperaments, we can get twelve Gong tones and sev-enty-two Diao tones, which are called eight-four modes of music, without the name of "xiaolv ru shuangjiao ( tone)".In the real music practice since the Sui and Tang Dynasties, not all the twelve Gong tones have been used, among which at most seven were applied.However, music scores of the traditional Chinese opera are usually named after nine Gong tones, and Qu tunes are also governed under the guide of nine Gong tones in compiling styles.In fact, although the name of nine Gong tones belongs to the category of music modes in royal court music, theories on its tones cannot be found in ancient books of the Ming and Qing Dynasties or scores of the Northern and Southern Dy-nasties."Xianlv ru shuangjiao ( tone)" is only a combination of tune names with no real meaning. Thus, the two remain in name only.Furthermore, the sequence of flute' s seven tones is often con-sidered as"not higher than wu, not lower than yi", while the statement of"not lower than shang, not higher than yi" in the"guide to the use of the book" of Suijin Cipu ( an independent tune book) refers to the order of scale.
