Here's a breakdown:
* Sch: Pronounced like the "sh" in "ship"
* a: Pronounced like the "a" in "father"
* tz: Pronounced like the "ts" in "cats"
* i: Pronounced like the "ee" in "see"
It's important to note that the "z" sound is softer than the "z" in "zebra". Think of it as a "ts" sound with a bit of a hiss at the end.
