All of the scales that are supposed to make up a set in order to posit 'subset' are just a transposition of the one single thing. So to use the plural is really not so meaningful.fmr wrote:So, you have "a collection of scales" inside C Major?

This is "Music 101", you can't be any lower than this.
So, people use the word modes to refer to the collection of scales that share names with modes, in the parent's case, he referred to the six most common scales used in pop music. That set of "scales" is a subset of the set of scales that people deal with in pop music. Here subset is used correctly both in the lay sense, and in the mathematical sense.![]()
You can't have a "subset" of a single thing, even if you are math genius.
The modes are not a subset of scales; the name of modes as though they are simply scales is not different in this regard; if you confound them so that they are as meaningless as all this, they're all the same seven notes. Then there are eleven other statements of this same thing.
