10edo is notable for having close approximations of 15/14 to one step, and 13/8 to 7 steps. 10th-octave temperaments naturally occur between any equal divisions of the octave whose greatest common divisor is 10.

Temperaments discussed elsewhere include: decoid, deca, decal, decimetra, decistearn, decavish, and linus.

## Neon

Neon tempers out [21 60 -50⟩ in the 5-limit. Neon extensions discussed elsewhere include deca, calcium, and zinc.
