Pinyin Tone Marks: Reading ā á ǎ à, and Where the Mark Goes
The four tone marks are ā á ǎ à - level, rising, dipping, falling. The mark goes on an a or an e whenever the syllable has one, on the o in ou, and otherwise on the last vowel. ü keeps its dots after n and l and drops them after j, q, x and y. What no mark can tell you is what the syllable sounds like. Pleco will hand you the notation; the ear has to close the rest.
The four marks, and what each one claims
Pinyin writes a Mandarin syllable twice over. The letters give you the consonants and vowels; the small mark above one of the vowels gives you the tone. The second half is not decoration. 妈 mā, 麻 má, 马 mǎ and 骂 mà are four different words that share every single letter, and the only thing separating them on the page is a mark two millimetres tall.
| Mark | Tone | Shape | Example | Meaning |
|---|---|---|---|---|
| ā | First | High and level | 妈 mā | mother |
| á | Second | Rising | 麻 má | hemp |
| ǎ | Third | Low, dipping | 马 mǎ | horse |
| à | Fourth | Falling | 骂 mà | to scold |
| a | Neutral | Short, unstressed, no contour of its own | 吗 ma | question particle |
The four marks are drawings of the pitch, which is the one genuinely clever thing about the notation. The macron is flat, so the tone is flat. The acute goes up, so the tone goes up. The caron dips down and comes back, and the grave falls. Nobody has to be taught this mapping; you can read it off the shape, which is exactly why marks are easier to read at speed than the numbers people type instead. That trade-off has its own post - tone numbers or tone marks - because there are places where the numbers are the right answer.
Where the mark goes: three lines that cover the language
Every syllable carries exactly one mark, and there is never any ambiguity about which vowel gets it. The rule fits in three lines, applied in order:
- If there is an a or an e, it takes the mark. No pinyin syllable contains both, so this never conflicts with itself: hǎo, xiè, guài, biǎo, jiāng.
- Otherwise, if the syllable contains ou, the o takes it. gǒu, zhōu, dōu, ròu.
- Otherwise the last vowel takes it. liù, guì, duō, xiǔ, zǐ.
Two pairs cause almost all the mistakes, and they are the same pair reversed. iu ends in u, so the mark lands on the u: 六 liù, six. ui ends in i, so the mark lands on the i: 贵 guì, expensive. They look symmetrical and they are not, and writing líu or guí is the single most common pinyin typo among learners. One further mechanical detail: a mark on an i replaces the dot. It is nǐ, never nï.
It is worth knowing that this rule is not arbitrary bureaucracy. It puts the mark on the nucleus - the loudest, longest part of the syllable, the bit your voice actually sits on while the pitch does its work. In liù the weight is on the u and the i is a quick glide into it; in guì the weight is on the i and the u is the glide. So the placement rule is a small phonetic claim about where the tone lives, not just an orthographic convention. That is the most the notation ever tells you about the sound, and as claims go it is a modest one.
ü, and the four initials that make its dots disappear
ü is a genuine seventh vowel, not a decorated u. Say the vowel in see, hold it, and round your lips into a whistle shape without moving your tongue: that is ü. English has no such vowel, which is a whole problem of its own and gets its own treatment in why pinyin is not pronunciation. What concerns us here is only how it is written.
After j, q, x and y the dots are dropped and it is written as a plain u. jū, qù, xū, yǔ, juān, qún - every one of those is a ü. This is safe rather than sloppy, because those four initials never take a genuine u, so there is nothing for the plain letter to be confused with.
After n and l the dots stay, because here both vowels exist and the difference is the whole word:
| With u | Meaning | With ü | Meaning |
|---|---|---|---|
| 努 nǔ | to exert | 女 nǚ | woman |
| 路 lù | road | 绿 lǜ | green |
The tone mark sits on top of the dots rather than replacing them, giving the four least-typed characters in the system: ǖ ǘ ǚ ǜ. Few keyboards reach them directly, so the near-universal workaround is the letter v, which pinyin otherwise never uses: nv3 gets you nǚ in most Chinese input methods and dictionary search boxes.
The syllable with no mark is not the syllable with no tone
A bare vowel means the neutral tone, and the absence is information rather than an omission. It says: this syllable is short, unstressed, and takes its pitch from whatever came before it. 爸爸 bà ba, dad. 杯子 bēi zi, cup. 吗 ma, the question particle. Some dictionaries put a small dot before the syllable to make the neutral tone explicit; most leave it blank and expect you to notice.
This is also where the notation starts to come apart from the audio, and it is worth seeing early. Of the 637 clips in Tingyin's corpus, 80 contain a neutral tone and not one of them appears before level 3, because a neutral syllable cannot be played on its own - with nothing in front of it, it has no pitch to borrow.
The larger version of the same problem is tone sandhi. Written out, 你好 is nǐ hǎo: third tone, third tone. Said aloud it is ní hǎo, because a third tone before another third tone is pronounced as a second. Tingyin labels every clip with the tone as spoken rather than as written, and the consequence is stark - across all 637 clips there is not one tagged third-then-third, and sandhi is applied in 55 of them. The mark on the page and the pitch in the air are answering two different questions. The sandhi post works through all of the rules that do this.
A tone mark is a category label, not a sound
Here is the thing the charts leave out. ǎ tells you that this syllable belongs in the third bin rather than one of the other four. It does not tell you what frequency the speaker starts on, how far the pitch drops, whether it comes back up, how long the syllable lasts, or what any of that sounds like arriving unannounced in the middle of somebody else's sentence. It is a label on a category. Learning the label perfectly leaves the category itself completely empty.
Musicians do not confuse these two skills. Reading a note on the third line of the treble stave and naming it B is sight-reading; hearing a B and naming it is ear training. Every conservatoire timetables them as separate classes, and nobody expects the first to deliver the second. Mandarin learners routinely do expect it, because pinyin arrives on day one and looks like it is doing the job.
The gap widens once you leave isolated syllables. A fourth tone at the end of a sentence falls further than the same fourth tone in the middle of one. A low voice's first tone can sit below a high voice's third, so absolute pitch tells you nothing and only the shape within a speaker's own range counts. Speed compresses all of it. Through every bit of that, ā does not move a pixel - which is exactly what makes it useful notation and useless training.
There is a quick way to find out which skill you have. Read a page of marked pinyin aloud; you will probably do fine. Then play a sentence you have never seen written and try to say what tones went past. If the second collapses, that is not a failure of the marks - they did all their work on the page, which is the only place they exist. It is the reason tones are hard to hear rather than hard to say.
Filling the category the mark only names
The notation is worth learning properly, and you now have all of it: four marks, a three-line placement rule, the ü cases. That is a morning's work, after which the marks are solved for good. What follows is the part that takes longer.
Turn reading into prediction
Commit to what you expect before you press play, so that reading a mark becomes a checkable guess rather than a look-up. Being wrong out loud is where the learning is; a silent nod at a correct answer teaches almost nothing.
Practise identification with the pinyin covered
If the marked syllable is visible while you listen, you are reading, not listening - the answer is sitting on the page and your ear will happily take the shortcut. Hear first, commit, then look.
Start where the only variable is the tone
Minimal pairs - the same syllable in two different tones, back to back - isolate the thing you are trying to hear. Tingyin's level 1 is exactly this and nothing else: 80 single-syllable clips, each syllable presented in its several tones, free with no account and no sign-in. Level 2 adds 200 more single syllables and is free once you sign in. Levels 3 and 4 move to real words - 237 two-syllable, 107 three-syllable and 13 four-syllable clips - and those are the paid tier, which also carries progress sync across devices and offline downloads. On the web that is $2.49 weekly, $5.99 monthly, or $15.99 once for lifetime access.
Since the argument here is that the sound matters more than the notation, one detail about the audio: every clip that ships is a recording of a person, not a synthesised rendering of the mark. That is the whole point - a tone mark is a label, and what you need in your ear is what a speaker did with it.
None of which replaces the other things you need. Pleco is the dictionary to reach for when you meet a word in the wild and want its marks. Anki will do contrastive drilling too if you are willing to build the deck and find the audio. And no listening trainer can tell you whether your own fourth tone is falling far enough - for that you need a person, which is what italki and a tutor are for. Tingyin cannot hear you speak, and it never claims to. You can start the drill without an account and find out in ten minutes whether identification is the skill you are missing.
Frequently asked questions
Where does the tone mark go in pinyin?
On the a or the e if the syllable has one - they never both appear, so there is no conflict. If neither is present but the syllable contains ou, the o takes it. Otherwise the last vowel takes it, which is why it is liù but guì. A mark on an i replaces the dot: nǐ, not nï. Pleco will show you the correct placement for any word you look up.
What do the four tone marks ā á ǎ à actually mean?
They name which of five tone categories a syllable belongs to: high level, rising, low dipping, falling, and unmarked for neutral. The shapes are pictures of the pitch, which makes them easy to read. What they do not encode is any of the detail - starting frequency, how far the pitch moves, duration, or how the tone changes at speed. Reading the mark and identifying the tone by ear are separate skills, as HelloChinese users who can read pinyin fluently and still mishear speech tend to discover.
Why does ü sometimes lose its dots?
Because after j, q, x and y there is nothing to confuse it with - those initials never take a plain u, so ju, qu, xu and yu are unambiguously ü and the dots are redundant. After n and l both vowels occur and the dots are load-bearing: nǔ is to exert and nǚ is woman, lù is road and lǜ is green. To type them, use v - nv3 produces nǚ in most input methods, since v is otherwise unused in pinyin.
Can I learn pinyin with tones without learning characters?
Yes, and for listening practice it is a reasonable order to work in - the sound system is finite and closes quickly, while characters do not. Tingyin takes that route to its limit: it teaches no characters and no grammar at all, only tone identification from audio. If you want the character side, Duolingo and HelloChinese both build it in from the beginning, and Anki with a decent hanzi deck is the traditional route.
Do tone marks tell me how to pronounce a word?
They tell you which tone to aim for, not how to hit it or how to recognise it. And the mark is not always what a speaker produces: two third tones in a row come out as second-then-third, so nǐ hǎo is said ní hǎo. Tingyin labels its clips by what is spoken rather than what is written, which is why no clip in the corpus is tagged third-then-third. For feedback on your own production you need a human - italki or a tutor. Tingyin cannot hear you.
