Flutterby™! : It's been a long time since high school

It's been a long time since high school French, and I'm not sure I can trust any of the online pronunciation guides since they don't match my memory on several other words, but a special "fuck you" to the sheet music writer who wrote "peine" with the "pein" on a quarter note, and the "-e" on a whole note, because I don't think there's any way to actually pronounce this appropriately that way.
