Lesson 3 · The six tones & where the marks go

Every Vietnamese syllable carries a tone — six tones, five written marks (the level tone has none). “Thanh” is the melody you say; “dấu” is the symbol you write. Change the tone and you change the word, so this lesson trains your ear and your mouth.

🎼 The pitch map

All six tones on one stage. Tap a tone to hear “ma” spoken with it and watch its pitch line light up.

✍️ Where does the mark go?

The tone mark always sits on a VOWEL, never a consonant. Three rules cover everything:

1 · One vowel

the mark goes right on it

mã · mình · bn · cùng

2 · Vowel cluster, no final consonant

the mark goes on the second-to-last vowel

hòa · kiểu · khe · mùa

3 · Vowel cluster + final consonant

the mark moves to the last vowel

tiếng · Vit · Nguyn · Qunh

You will meet both “hòa” and “hoà” in the wild — an older convention puts the mark on the last vowel of open pairs. Both are accepted, and when you type with Telex (Lesson 2) the keyboard places the mark for you, so you never have to choose.

🎯 One sound, six meanings

This is why tones matter: the same syllable with six tones is six different words. Tap through both families.

👂 The three confusable pairs

Learners mix up these three pairs the most. Hear each tone on “ma” first, then on real words — every chip plays audio.

thanh sắc

Sắc rises clean and smooth — like a surprised “what?!”, air flowing freely all the way up.

thanh ngã

Ngã rises too, but the throat pinches shut mid-way — the sound “breaks” for a beat, then finishes the climb.

thanh ngang

Ngang holds one steady level. The trap for English speakers: we drop our voice at the end of words — don’t.

thanh huyền

Huyền eases downward — exactly the relaxed fall English uses at the end of sentences, which makes it the easiest tone of all.

thanh hỏi

Hỏi dips and comes back up — the sound of double-checking something. Practice trick: pinch your nose so the air leaves only through your mouth.

thanh nặng

Nặng drops low and stops short — close the throat and let only a sliver of air escape. Nail that little choke and the tone takes care of itself.

🎧 Tone quiz

10 questions — hear a word, pick the one you heard. Six choices, one per tone, and a different word family each question.
