'''46/45''' or the '''23rd-partial chroma''' is a [[superparticular]] interval of about 38.1 [[¢]]. It is the formal comma used to express 23-limit intervals in [[Ben Johnston's notation]], being expressed with a "23", while its reciprocal is denoted as <span style="display: inline-block; transform: rotate(180deg)">23</span> (a turned 23).

== Sagittal notation ==
== Notation ==
In the [[Sagittal]] system, this comma (possibly tempered) is represented by the sagittal {{sagittal | /|~ }} and is called the '''23/5 small diesis''', or '''23/5S''' for short, because the simplest ratio it notates is (4·5):23, as for example in C:D&#x200A;{{sagittal | /|~ }}. The downward version is called '''5/23S''' or '''23/5S up''' and is represented by {{sagittal| \!~ }}.
=== 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 {{invert|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.
