Ka- bahs Piah-no
But don't draw out the "ah in Piano. It's more of an inflected "no" than "ah"
Popincourt is difficult to pronounce if you don't know how to make the french sounds.
Poe-pin-coor
"Pin" sounds like how you pronounce the "i" in the word "Interesting" like and "ieh"
And Court is pronounced "Coor" like Coors Light, without the "s"
And without the harsh "r" sound at the end... Coor, with a soft r.
Haut is the same french sound as Haute as in "Haute Couture"
Almost like you are calling someone a "ho" but bring your tounge to the roof of your mouth in a soft "t" at the end of the word.
Ack.
Hope this is helpful and not more confusing.
