Notation

Ben Johnston's notation

This interval is the 23rd-partial chroma (23-limit formal comma) used to express 23-limit intervals in Ben Johnston's notation, being expressed with a "23", while its reciprocal is denoted as 23 (a turned 23). If the base note is C, then 23/16 is represented by C–F#+23. Note the + (for 81/80) is required.

Sagittal notation

In the Sagittal system, this comma (possibly tempered) is represented by the sagittal ⁠ ⁠ and is called the 23/5 small diesis, or 23/5S for short, because the simplest interval it notates is 23/5 (equiv. 23/20), as for example in C-D⁠ ⁠⁠ ⁠. The downward version is called 5/23S or 23/5S down and is represented by ⁠ ⁠.
