The septendecimal comma is significant in the [[Functional Just System]] as the 17-limit formal comma which translates a Pythagorean interval to a nearby septendecimal interval. Consequently, 17/16 is represented as a minor second. In the 2020 version of [[Helmholtz-Ellis notation]], however, that role is taken by [[2187/2176]], so 17/16 is represented as an augmented unison. | The septendecimal comma is significant in the [[Functional Just System]] as the 17-limit formal comma which translates a Pythagorean interval to a nearby septendecimal interval.

In the [[Sagittal]] system, this comma (possibly tempered) is represented by the sagittal {{sagittal | ~|( }} and is called the '''17 comma''', or '''17C''' for short, because the simplest interval it notates is 17/1 (equiv. 17/16), as for example in E-F{{nbhsp}}{{sagittal | ~|( }}. The downward version is called '''1/17C''' or '''17C down''' and is represented by {{sagittal| ~!( }}. | |||
