Interesting and helpful observations, as always! Sorry it took me a while to respond. I've been ill for a solid week (not COVID, thankfully), but am starting to feel better. In time, I may update this entire article, as so much could be added.

The 61-key minimum was only my personal preference, of course. It's interesting that you brought up musical styles. I'm a ragtime composer, which rarely lends itself well to practice on smaller keyboards. But, you're right, there's plenty of baroque music out there.

I tend to travel for months at a time, though, so for me it's just a preference. I'd rather not jump to baroque for, say, 3 months, if I didn't have to.

My joke about there being a million 49-key options was just a joke. I'd never seriously looked. So, thanks for your input there, and I'll certainly use it if/when I update this. I'm not sure when that will be as I'm still recuperating from being ill lately, and I'm still waiting to see if I can get my $$$ back from the scammers who didn't send me the folding piano.

But you're right--I do agree that the folding piano shown is real. I just don't think there's a reliable way to purchase one of them. So many others have shown me how they too were scammed with this. How unfortunate, eh?
