14L 22s (12/1-equivalent)

Revision as of 14:48, 10 February 2025 by 2^67-1 (talk | contribs)

Assume hemipyth[10] nominal names and intervals unless otherwise stated.

The 7L 11s (√12-equivalent) scale, also greater pochhammeroid (see below), greater colianexoid, greater f-enhar electric or greater f-enhar smitonic is a MOS scale. The notation "<√12>" means the period of the MOS is √12, disambiguating it from octave-repeating 7L 11s. The name of this period interval is called the oktokaidekatave. It is also equivalent to 14L 22s <12/1> and is the notation used in the scale tree. Its basic tuning is 25ed√12 or 50ed12.

The generator range is 597 to 615 cents (5\18<√12> to 2\7<√12>). The dark generator is obviously its √12-complement. Because this is a perfect eighteenth-repeating scale, each tone has an √12 perfect eighteenth above it.

The equave can range from 24/7 to 7/2, including the pure-hemipyth √12 and 1/QPochhammer[1/2]. It is because of the latter constant that Cole proposes naming this scale greater pochhammeroid.

Standing assumptions

The TAMNAMS system is used in this article to name 7L 11s <√12> intervals and step size ratios and step ratio ranges.

The notation used in this article is 0 Pacific-Hemipyth = 0123456789ABCDEFGH (see the section on modes below), unless specified otherwise. (Alternatively, one can use any octodecimal digit set as the numbers, as long as it is clear which set one is using.) We denote raising and lowering by a chroma (L − s) by # and f "flat (F molle)".

Modes

For clarity, each mode is split up into three pentachords and a trichord. There are three modes which defy this classification, having pentachords with one large step and four small steps. However, they are still included for completeness.

An ambiguous mode is named after the two pentachords in its first dekatave. The others are named after a certain 'core' or first-wave member of the Colian Nexus.

Scale tree

  Template: Scale tree is deprecated. Please use Template: MOS tuning spectrum instead. Details:
Use of a single Comments parameter has become unmaintainable. Existing scale trees should be migrated to the new template, where comments are entered using a step ratio p/q as a parameter:
{{MOS tuning spectrum
| 3/2 = Example comment
| 4/3 = Another example comment
}}


The parameters tuning and depth have been replaced with Scale Signature and Depth, respectively.
