| Bright Gens Up || No (optional) || The number of bright generators going up needed to produce the mode for which notation is applied. In [[UDP notation]], this corresponds to the value u in the UDP of u|d, or up (u times p) in the UDP of up<nowiki>|</nowiki>dp for multi-period mosses. If left blank, then the brightest mode is used by default.

The typical use of this template is for describing a mos's gamut, the set of named notes, with accidentals.

A scale signature different from the page's title can be specified as shown below.
A scale signature different from the page's title can be specified as shown below. This produces a gamut using the step ratio 2/1 and the brightest mode.


<pre>{{MOS gamut|Scale Signature = 4L 3s}}</pre>
<pre>{{MOS gamut|Scale Signature = 4L 3s}}</pre>
{{MOS gamut|Scale Signature = 4L 3s}}
{{MOS gamut|Scale Signature = 4L 3s}}


This produces a gamut with a step ratio of 2:1 for the brightest mode. Since it's common to use different step ratios and to apply notation to a different mode, an example of overriding the mode and step ratio is shown below.

An example of using a different step ratio and mode are shown below.

Equivalent pitch classes, such as enharmonic equivalents, are currently limited to pitches that fall at the exact midpoint of two other pitches, such as C# and Db being equivalent in standard notation, or C and B# being equivalent. This is to ensure note names have as few accidentals as possible.

Accidentals smaller than a chroma, such as [[ups and downs notation|ups and downs]] or half-accidentals, are currently not supported. An example of such usage is 5L 2s in 31edo, where Dbb may be notated as ^C (up-C) or Ct (C half-sharp).

If a step ratio is entered without being simplified, the edo (or ed{{angbr|equave|}}) displayed will reflect that by being a larger division of the equave. An example of this is 5L 2s in 24edo, whose step ratio is 4/2. However, notation for the additional notes, which may be notated using ups and downs, are currently not added to keep the output simplified.
