This is a work in progress…
The subminor scale is my name for a minor scale built from overtones, but with the root of the scale starting on the 3:2 instead of the 1:1. For example, consider an overtone series on F. The 3:2 above F is C. If the scale is based on a mode starting on C, as shown in the graph above, you have the subminor scale.
As with all overtone series, a cluster of notes above a certain pitch will always generate a difference tone. But even though the scale designed to favor the root at C, the difference tone will always be F. I will have to take that into consideration when I add low notes. They will have to resolve that F to C, and choose notes carefully to minimize the difference tone prominence.
