This questions is about scales. Scales are not a normal topic of the Music Fans site and Music SE handles questions about scales all the time.
Music SE also does have history questions and while there are some areas of overlap between the two SE this question seems a lot better fit for Music SE and there are distinct lines in the sand to be drawn between them. For example the history of a chord progress does not make sense here as it involves in depth progression knowledge and more fit for Music SE, but asking what the first instrument a musician/composer used is much more of a general Music Fan SE question and less practice and theory focused.
Our FAQ even states for history questions:
- **The history of songs and musicians/bands/artists/composers/songwriters/etc.**
- Song meanings and the origins of lyrics
- Terminology used in the music industry
- **Use, explanation, and history of music technology, devices, and media**
- Information about music memorabilia and the collection of it (e.g. “How rare is X?”)
Of the two bullet points that cover history it only covers history of songs, musicians/bands/artists/composers/songwriters/etc(the people behind the music), and music technology, devices, and media. This does not touch the history music theory ideas or music practice terminology and constructs.
In the answer you can even see it has nothing to do with the person in question. This would be akin to asking if Bono came up with the idea of making charities. Yes some questions about Bono and his charity may occasionally be on topic here, but the history of charities alone is not. Scales are much closer to our core topics, but because this is a fan site and not a site for musicians I do not see it as making sense here.
As a side note, this question is not a very good starting point for this debate as the user has a history of posting Music SE question here because they are suspended on Music SE and they were suspended here due to this issue.
