19edo Scale List

Here is a list of all heptatonic (7 note) scales possible in 19-equal-divisions-of-the-octave (19edo). Enjoy!

Explanation:

"Scale Num" = Scale catalog number. Scales are numbered from flattest to sharpest, from 1 to 18564.

"S1" .. "S7" = Step size in 19edo steps. 1 19edo step is a diminished step, 2 19edo steps is a half step and 3 19edo steps is a whole step. 4 19edo steps is an augmented step, and anything larger than that is a degree of extended step.

"Family" = Scale family. For example, the seven church modes of classical music theory consist of one family. Likewise, and scale can be cycled through like modes to generate a family of related scales.

"2" .. "7" = Interval or scale degree. b2 means minor second, bb2 is diminished second, 2 is major second, #2 is augmented second, etc. Anything with more than 4 flats will be written with the number of flats, a capital B, and then the interval. Likewise for sharps, but with capital B replaced with capital X.

"X Ref" = Cross reference in 12edo. Since there are far more 19edo scales possible, most of the time, this field will be blank. Otherwise, the catalog number is given in the form 12-7-family number-scale number. For example 12-7-49-344 is the 344th scale, which is in family 49, from the list of 12edo 7-tone scales.

"Scale name" = The name of the scale, as this author is most aware. Many scales have several different names, which can be confusing, but I tried to go with the most common one. This is most often blank, because most of the scales cataloged here have likely never been used before, at least in any way documented.

"Alias" = The second most common name associated with the scale, as best as the author is aware.

"Family name" = The name of the family of scales. This is left blank unless there is some data in either the X Ref or Scale name fields, with a few exceptions.
