The American Seceratary of State plays quite well, I saw a video of a slow movement from the Brahms d minor Violin and Piano Sonata.
The fact of the matter is that classical piano is largely a rich persons avocation. Pianos, their maintenance, GOOD piano instruction, these are expensive propositions! And this was not available for most Blacks until recently. A big exception, Duke Ellington, whose father was the White House butler; Duke made the best of a good situation, still with the odds against him. Until the emergence of the Asian economic juggernaut of the past 40 or so years, the planet's monetary wealth has been confined to European and white North American society. Things are changing. I bemoan the lack of cultural education in our schools and in media and in society. Why should any kid, of any background want to be a Classical Concert Artist? Dead white man music; how uncool is that? And that's how it seems to a lot of kids, that's how academia and the media portray it. Oh, and the "practical" side of society says "Make money"! Don't waste your life doing that, no one cares, you've got to make a living"
Making a dying is more like it.
Anyway, there's your list. If you want to do something to rectify this state of affairs, you could teach a talented minority student free of charge, or through a state or federal government fund and or program; these things exist, at least they did and probably still do in Massachusetts, and I'm sure in other states too.
