m Summary for xen-math nerds: Added the new scales
Line 3,368: Line 3,368:
Pinetone scales are built via step nesting from the 5-limit minor seventh tetrad: 6/5 3/2 9/5 2/1. The bounds for its scales are the set of temperings of the rank-3 step-nested children of the 4-note SNS 6/5 3/2 9/5 2/1. Pinetone diminished scales are built via step-nesting from the 5-limit diminished tetrad: 6/5 36/25 5/3 2/1. The bounds for its scales are the set of temperings of the rank-3 step-nested children of the 4-note MOS scale 6/5 36/25 5/3 2/1.

The Pinetone chromatic is a 12-note rank-3 [[Meantone]][12] x [[Ripple]][12] [[Fokker block]], a [[step-nested scale]] that also tempers to [[Porcupine]][8], comprising a diatonic [[Meantone]][7]-[[Porcupine]][7]-[[Dicot]][7] [[wakalix]] / 3-[[Step-nested scale|SNS]] on the white keys, and a pentatonic [[Meantone]][5]-[[Father]][5]-[[Bug]][5] [[wakalix]] on the 'black' keys.

For the accompanying mapping for the Lumatone keyboard the G♯ / A♭ key is coloured pink (and the remaining chromatic keys blue), and along with the white keys makes a [[Porcupine]][8] / [[Father]][8] [[Fokker block]] (any colours could be chosen instead of white, pink, and blue).

The Pinetone diatonic is a [[wakalix]] (pairwise well-formed scale) and a [[step-nested scale]]: A detempering of [[Meantone]][7] and [[Porcupine]][7], (and also of [[Dicot]][7]), a [[Fokker block]] (product word) with [[Unison vector|unison vectors]] of [[81/80]] and [[250/243]] (and [[25/24]]) comprising 1 large step of 9/8 (''L'' x ''L''), 3 medium steps of 10/9 (''L'' x ''s''), and 3 small steps of 27/25 (''s'' x ''s'').

As a product word of 5L 2s (standard diatonic scale form) and 1L 6s (Porcupine[7] scale form) the Pinetone diatonic in it's symmetric mode msmLmsm = LsLLLsL x sssLsss, a product of Dorian mode of the standard diatonic scale, and the symmetric minor mode of the Porcupine[7] scale form.


The Azurian bright minor, Duradian dark minor, Karakalian bright minor, Phyradian dark minor are alternative heptatonic subsets of the Pinetone chromatic — Fokker blocks of the same unison vectors and step sizes as the Pinetone diatonic arranged in different patterns, corresponding to product words of different combinations of modes of Porcupine[7] and Meantone[7]. Unlike the Pinetone diatonic, these scales are not also Fokker blocks of Dicot[7] with Porcupine[7] or Meantone[7].

The Pinetone major and minor-harmonic octatonics are the 8-note rank-3 [[Porcupine]][8] x [[Father]][8] [[Fokker block|Fokker blocks]] with [[Unison vector|unison vectors]] of 250/243, 16/15, and 648/625; comprising 4 large steps of 10/9 (''L'' x ''L''), 3 medium steps of 27/25 (''L'' x ''s''), and one small step of 25/24 (''s'' x ''L'').
