纯律

按照大三和弦关係'依次产生音序（五声，七声，12音）的生律方式， 例如： 纯五度加大三度组成大七度；纯五度减大三度组成小三度[2]。

该方法产生的音阶与十二平均律、五度相生律有着细微的差异。纯律与五度相生律均基于自然泛音音程[2]，这是它们不同于十二平均律之处。

純律即取1、${\displaystyle {\frac {16}{15}}}$(或${\displaystyle {\frac {256}{243}}}$)、${\displaystyle {\frac {9}{8}}}$、${\displaystyle {\frac {6}{5}}}$(或${\displaystyle {\frac {32}{27}}}$)、${\displaystyle {\frac {5}{4}}}$(或${\displaystyle {\frac {81}{64}}}$)、${\displaystyle {\frac {4}{3}}}$、${\displaystyle {\frac {7}{5}}}$(或${\displaystyle {\frac {45}{32}}}$、${\displaystyle {\frac {64}{45}}}$)、${\displaystyle {\frac {3}{2}}}$、${\displaystyle {\frac {8}{5}}}$(或${\displaystyle {\frac {128}{81}}}$)、${\displaystyle {\frac {5}{3}}}$(或${\displaystyle {\frac {27}{16}}}$)、${\displaystyle {\frac {7}{4}}}$(或${\displaystyle {\frac {16}{9}}}$)、${\displaystyle {\frac {15}{8}}}$(或${\displaystyle {\frac {243}{128}}}$)、2為數列。

• 一种观点认为该法由毕达哥拉斯的整理完成[3]。

印度音乐的22个“什鲁蒂”其实也就等于取数列1、${\displaystyle {\frac {256}{243}}}$、${\displaystyle {\frac {16}{15}}}$、${\displaystyle {\frac {10}{9}}}$、${\displaystyle {\frac {9}{8}}}$、${\displaystyle {\frac {32}{27}}}$、${\displaystyle {\frac {6}{5}}}$、${\displaystyle {\frac {5}{4}}}$、${\displaystyle {\frac {81}{64}}}$、${\displaystyle {\frac {4}{3}}}$、${\displaystyle {\frac {27}{20}}}$、${\displaystyle {\frac {45}{32}}}$、${\displaystyle {\frac {64}{45}}}$、${\displaystyle {\frac {3}{2}}}$、${\displaystyle {\frac {128}{81}}}$、${\displaystyle {\frac {8}{5}}}$、${\displaystyle {\frac {5}{3}}}$、${\displaystyle {\frac {27}{16}}}$、${\displaystyle {\frac {16}{9}}}$、${\displaystyle {\frac {9}{5}}}$、${\displaystyle {\frac {15}{8}}}$、${\displaystyle {\frac {243}{128}}}$、2。故1什鲁蒂相当于五度律半音、2什鲁蒂相当于纯律半音、3什鲁蒂相当于小全音、4什鲁蒂相当于大全音……
