Mr Babs is a drummer and as one can imagine, the name Paiste is pretty common around the house.
How exactly do you pronounce it?
I heard, for ages: “Paste” or “Paste-ee”.
After looking the name up, I find this to be wrong.
All sources agree that the first part is pronounced “pie” and that the accent is here.
The second part varies. I have seen some say it’s “steh” as in “Stella” while others say “stee” as in “steeple”.
The Paiste website doesn’t say and e-mails remain unanswered.
Say “Pie-stee” and you’ll have it right. Great cymbals BTW. Love playing mine.
Quasi
He should just simplify things and switch to Zildjian! 
Actually, he does use Zildjian cymbals.
We just always see Paiste stuff.
I’ll second Quasi and say I’ve always heard “pie-stee”. My first set of hihats were Paiste, I traded them in on some Sabians, but the crash/ride was a Zildjian, and the set I just bought is from the Zildjian ZXT line. I think I’ll stick with them.
Actually, it’s pronounced “Throat-Warbler Mangrove.”
