Template:MOS gamut/doc
Parameters
| Parameters | Required? | Description |
|---|---|---|
| Scale Signature | Yes (optional on mos pages) | The mos's scale signature in the form "xL ys", or for non-octave mosses, "xL ys<p/q>", "xL ys⟨p/q⟩", or "xL ys (p/q-equivalent)". If left blank and used on a mos page, then the page's title will be used. |
| Step Ratio | No (optional) | The step ratio of the mos, denoted as a fraction p/q. If not simplified, then the ratio is automatically simplified. If left blank, then the step ratio 2/1 is used by default. |
| Bright Gens Up | No (optional) | The number of bright generators going up needed to produce the mode for which notation is applied. If a mode is denoted using its UDP (up|dp), this is the value up (u times p). If left blank, then the brightest mode is used by default. |
| Note Symbols | No (optional) | A string of note symbols, such as CDEFGAB (for standard notation) and JKLMNOP (for diamond-MOS notation). This should be entered as a string, where one character is one note name. If left blank, then standard notation (for 5L 2s) or diamond-MOS notation (for anything else) is used by default. |
| Sharp Symbol | No (optional) | The symbol used to denote raising by a chroma, usually a sharp (#) or diamond-MOS's am/amp symbol (&). If left blank, then either # or & is used by default. |
| Flat Symbol | No (optional) | The symbol used to denote lowering by a chroma, usually a flat (b) or diamond-MOS's at symbol (@). If left blank, then either b or @ is used by default. |
Usage
The typical use of this template is for describing a mos's gamut, the set of named notes, with accidentals.
{{MOS gamut}}
A scale signature different from the page's title can be specified as shown below.
{{MOS gamut|Scale Signature = 4L 3s}}
J, J&/K@, K, L, L&/M@, M, N, N&/O@, O, P, P&/J@, J
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.
{{MOS gamut|Scale Signature = 4L 3s|Bright Gens Up = 3|Step Ratio = 3/1}}
J, K@, J&, K, L, M@, L&, M, N, O@, N&, O, P, J@, P&, J
{{MOS gamut|Scale Signature = 4L 3s|Bright Gens Up = 3|Step Ratio = 3/2}}
J, J&, K@, K, K&/L@, L, L&, M@, M, M&/N@, N, N&, O@, O, O&/P@, P, P&, J@, J
Using different notation
An example of this template's usage with different notation can be shown using Armodue notation (used for 7L 2s) and notation used for Lambda (3/1-equivalent 4L 5s).
{{MOS gamut|Scale Signature = 7L 2s|Bright Gens Up = 7|Note Symbols = 123456789|Sharp Symbol = #|Flat Symbol = b}}
J, J&/K@, K, K&/L@, L, M, M&/N@, N, N&/O@, O, O&/P@, P, Q, Q&/R@, R, R&/J@, J
{{MOS gamut|Scale Signature = 4L 5s (3/1-equivalent)|Bright Gens Up = 5|Note Symbols = CDEFGHJAB|Sharp Symbol = #|Flat Symbol = b}}
J, K, K&/L@, L, M, M&/N@, N, O, O&/P@, P, Q, Q&/R@, R, J
Limitations
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 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).
{{MOS gamut|Scale Signature = 5L 2s|Step Ratio = 5/3}}
J, K@@, J&, K@, J&&, K, L@, K&, L, M@@, L&, M@, L&&, M, N@@, M&, N@, M&&, N, O@@, N&, O@, N&&, O, P@, O&, P, J@@, P&, J@, P&&, J
If a step ratio is entered without being simplified, the edo (or ed⟨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 for the sake of keeping the output simplified.
{{MOS gamut|Scale Signature = 5L 2s|Step Ratio = 4/2}}
J, J&/K@, K, L, L&/M@, M, M&/N@, N, N&/O@, O, P, P&/J@, J
This template can accept equalized step ratios, but collapsed step ratios result in an improperly formatted table. This is an aesthetic issue.
{{MOS gamut|Scale Signature = 5L 2s|Step Ratio = 1/0}}
J, K/L, M, N, O/P, J
The design of the template itself is not finalized and is open to suggestions.
