Not sure what HIP stands for. SBCO aren't really a dedicated baroque orchestra, it's just a name. They are completely private, without government support or major benefactors - an extraordinary feat in China - and play whatever gigs they can get.
I didn't get the impression that "authentic performance practice" was much of a thing in China while I was there. Hopefully that's changing, if slowly.
Interesting. Given that there are plenty of baroque ensembles in Japan and they are also cropping up in Korea, Hong Kong and Singapore, I'm sure China will follow. Already many excellent classical musicians coming from China. What instrument do you play?
HIP = Historically Informed Performance. A more posh way of saying "period instruments" but it seems to have become the accepted term. Easier to tweet.
