This tone exists, but no HSK 1–3 word uses it yet — practise the sound on its own.

Hold one steady high note, like a doctor’s “aaah”. English has no flat pitch, so it will feel unnaturally robotic — that is correct.

错cuò — mistake

不错bù cuò — correct

Start at the top and drop fast, like a firm “No!”. Short and decisive.

The initial: c

[tsʰ]

What the mouth does: Same “ts” as z, released with a strong puff of air.

Closest English sound: The “wo” in “won’t”.
