-'''Lefts and rights notation''' is a notation for [[just intonation]] primarily developed by [[User:CompactStar|CompactStar]]. It represents every just interval as a sequence of lefts/rights and a diatonic degree.

-== Explanation ==
-All intervals are given a diatonic degree, calculated from their [[7edo]] [[patent val]] [[mapping]]. If k is a degree, the central k-th is the simplest (according to [[Tenney height]]) just ratio which is a k-th. For example, the central 3rd is [[5/4]], since it is the simplest 3rd, and the central 7th is [[7/4]], since it is the simplest 7th. The left k-th is the simplest  k-th which is flatter than central, and the right k-th is the simplest k-th which is sharper than central. Central, left and right are abbreviated as c, l, and r respectively.
-Left and right can be used multiple times to produce more complex qualities. For example, leftleft is flatter than left, leftright is between left and central, rightleft is between central and right, and rightright is sharper than right. In general, adding a left always means to go flatter, and adding a right always means to go sharper, with each added left/right becoming increasingly smaller in their effect.
