I'm really happy this is being shared so widely! Think about this for a minute: how many of us didn't know this existed? Why? https://twitter.com/MusicoloJake/status/1275156195100123136
Despite being such a valuable resource for musicologists and music theorists and historians, it was published by the American Society for Aesthetics, not exactly a name that's on all of our radars.
And that's because the ASA has Diversity Curriculum Grants, which is what Jenkins received in order to do the incredible work that he did https://aesthetics-online.org/page/CurriculumGrants
The @ams_musicology doesn't have any kind of Curriculum development grants at all, let alone one devoted to diversity
Yes, the AMS does great work with their grants, but they're almost all geared towards research or conference attendance.
