| | The '''graviton''' ({{monzo|legend=1| -13 17 -6 }}, [[ratio]]: 129140163/128000000) is a [[5-limit]] [[comma]] of about 15.353¢. It belongs to the [[syntonic–chromatic equivalence continuum]] and is equal to the difference between a stack of six [[syntonic comma]]s and an [[apotome]] ((81/80)<sup>6</sup>/(2187/2048)), or in terms of classic chromatic semitone, between a stack of four syntonic commas and a classic chromatic semitone ((81/80)<sup>4</sup>/(25/24)). It is also the [[schisma]] times the [[sensipent comma]] and the [[parakleisma]] times the [[semicomma]]. Tempering it out leads to the [[gravity family]] of temperaments. [[Patent val]]s which temper it out include those for {{EDOs| 7, 58, 65, 72, 130, 137, 202 and 346 }}. |
