A library for generating microtonal scales inspired by work and theories of Erv Wilson.
This library has several different namespaces each corresponding to a different type of scale.
For an introduction to CPS scales: http://www.anaphoria.com/hexany.pdf https://en.xen.wiki/w/Combination_product_set
(require '[erv.cps.core :as cps])
(def my-hexany (cps/make 2 [1 3 5 7]))
(-> my-hexany
+all-subcps ;; add all subsets under the `:subcps` key
)For an introduction to MOS scales: https://www.anaphoria.com/mos.pdf https://anaphoria.com/wilsonintroMOS.html https://en.xen.wiki/w/MOS_scale
(require '[erv.mos.core :as mos]
'[erv.mos.submos :as submos]')
(def period 31)
(def generator 13)
(def my-mos (mos/make period generator))
(submos/make-all-submos (nth my-mos 3) generator) ;; this will generate all secondary MOS and all possible "traverse" MOS
This library is a work in progress and mostly a workshop for myself, so the code is not polished as it should. If you are using this library, feel free to let make me aware of so that I can take more care of the code and the documentation.
