Off-topic submission: open-access music theory textbook, no summarizable content

The supplied source is not a cybersecurity or technology article. It is the landing page of “Music Theory for the 21st-Century Classroom,” an open-access music theory textbook hosted at the University of Puget Sound. No article body was provided beyond the title, so there is nothing substantive to condense.

Even if the full text were available, the subject — pedagogy for teaching musical scales, harmony, and notation — falls entirely outside this publication’s remit. It carries no security, infrastructure, policy, or technical-industry angle that would justify coverage. The only tenuous tech connection is that it is a free, web-based educational resource, which is not enough to build a story on.

Recommendation: do not run this. If it surfaced on Hacker News, it is likely of interest to that community for its open-educational-resource model, but it should be routed away from our cybersecurity/tech desk. I have not fabricated a summary of content that was not supplied.
