I think this was brought up before but I checked Tchaikovsky's page for who his wife was only to find no wikibox. A few composers like Bach or Handel have a very tiny one that only shows a few dates but most don't?
Why do no composers have a useful wikibox? Composer fans apparently gatekeep the hell out of composer pages and think wikiboxes are tacky and useless. Yet some composers have them and have had them for years now.
Oh, you do not
want to go down that rabbit hole right now.
TL;DR A long-ass fucking time ago, classical music enthusiasts decided their favourite musicians didn't need an infobox, even though it's customary across 99% of all other biographical pages, from actors to modern-day artists to politicians to criminals to fucking YouTubers even. There was a massive war over it, and those who campaigned against them won out. It makes zero fucking sense, but that's the way the cookie crumbled during that particular argument.
Oh, and here's a bit of inconsistency for you:
The name "Chevelle" was invented by a GM executive in the 1960s. It does not come from anywhere. The two black women (I use that term loosely for the boxer) named Chevelle were named after the car, as were the two bands. Anyone looking up "Chevelle" is, 99 times out of 100, looking up the car. Yet it takes you to a disambiguation page which is surely not needed, since anyone looking up any of the other four topics would have specified as such.
Now let's see what happens when one looks up "Mustang":
It goes straight to the page about the horse, even though given the universal popularity of both the car and fighter plane of the same name, it really should go to a disambiguation page, with either "Wild Mustang" or "Mustang (horse)" referring to the animal.
