Tones

Complete guide to Mandarin's 4 tones and neutral tone: tone shapes, mnemonics, tone sandhi rules for 3rd+3rd, 不, and 一, minimal pairs, and color coding conventions.

Mandarin Chinese is a tonal language: the pitch contour (shape of the voice pitch over a syllable) determines meaning. The same sequence of sounds, spoken with a different pitch pattern, is a completely different word. There are four tones plus a neutral tone (sometimes called the fifth tone).

Getting tones right from day one is essential. Bad tone habits are extremely difficult to correct after 6–12 months of practice.


The Five Tones

# Mark Name Pitch Shape Description Mnemonic Example
1 ā First tone High, flat (55) Hold a steady high pitch, like a musical note "Ahh" at the doctor — flat and sustained 妈 mā (mother)
2 á Second tone Rising (35) Pitch rises from mid to high, like a question "What?" in surprise — voice goes up 麻 má (hemp, numb)
3 ǎ Third tone Dipping (214) Pitch dips low then rises; full form sounds like a drawl "Huh?" with skepticism — dips then up 马 mǎ (horse)
4 à Fourth tone Falling (51) Pitch drops sharply from high to low "Stop!" with authority — quick drop 骂 mà (to scold)
0 a Neutral tone Short, light Unstressed and quick; no fixed pitch — influenced by preceding tone A quick murmur, barely said 吗 ma (question particle)

The numbers in parentheses (e.g., 55, 35) are Chao tone letters: a scale from 1 (lowest) to 5 (highest). Tone 1 is a sustained 5-5; Tone 2 rises from 3 to 5; Tone 3 goes 2-1-4; Tone 4 falls from 5 to 1.


The Classic Example: 妈麻马骂吗

The syllable ma across all five tones:

Pinyin Character Meaning
mother
hemp; numb; pockmarked
horse
to scold; to curse
ma question particle (yes/no)

This example is cited in virtually every Mandarin textbook precisely because it shows that tones are not optional decoration — they are the word.


Color Coding Convention

Many learners and apps use a standard color scheme to visually mark tones:

Tone Color Hex
Tone 1 Red #E74C3C
Tone 2 Orange / Yellow-orange #E67E22
Tone 3 Green #27AE60
Tone 4 Blue #2980B9
Neutral Grey #95A5A6

This convention is used in Pleco, Anki decks, and many Chinese learning apps. Consistent use helps your brain associate pitch with color quickly.


Tone Sandhi Rules

Tone sandhi refers to regular, predictable changes in tone that happen in connected speech. These are not exceptions — they are rules that apply every time the conditions are met.

Rule 1: Third + Third → Second + Third

When two third-tone syllables occur in sequence, the first changes to a second tone in speech (but is still written as third tone in pinyin).

Written Pinyin Spoken Example Meaning
nǐ hǎo níhǎo 你好 Hello
kě yǐ kéyǐ 可以 can; may
wǒ yě wóyě 我也 I also
lǎo shǔ láoshǔ 老鼠 mouse (animal)

Note: The written pinyin always shows the underlying (dictionary) tones. Only in speech does the first third tone become second. Dictionaries and textbooks write 你好 as nǐ hǎo, not ní hǎo — but you pronounce it ní hǎo.

In a sequence of three or more third tones, the pattern depends on phrasing and stress. Generally, every third tone except the last in a phrase is raised toward second tone.


Rule 2: 不 (bù) Tone Change

The negation word 不 is normally fourth tone (bù). Before another fourth-tone syllable, it changes to second tone (bú).

Before Tone of 不 Example Pinyin Meaning
4th tone 2nd (bú) 不是 bú shì is not
4th tone 2nd (bú) 不对 bú duì incorrect
1st tone 4th (bù) 不喝 bù hē don't drink
2nd tone 4th (bù) 不来 bù lái not coming
3rd tone 4th (bù) 不好 bù hǎo not good

Shortcut: 不 becomes second tone only before fourth tone. Before everything else, it stays fourth.


Rule 3: 一 (yī) Tone Change

The number 一 (one) is normally first tone (yī). It changes in context:

Position Tone of 一 Condition Example Pinyin Meaning
Before 4th tone 2nd (yí) 一个 yí gè one (of something)
Before 4th tone 2nd (yí) 一样 yí yàng same
Before 1st tone 4th (yì) 一天 yì tiān one day
Before 2nd tone 4th (yì) 一年 yì nián one year
Before 3rd tone 4th (yì) 一起 yì qǐ together
Ordinal use 1st (yī) 第一, phone numbers, addresses 第一 dì yī first
Standalone 1st (yī) Counting, listing 一, 二, 三 yī, èr, sān one, two, three

Pattern summary: 一 before fourth → second (yí); 一 before first/second/third → fourth (yì); in ordinals and isolated form → stays first (yī).


Neutral Tone

The neutral tone (also called the "fifth tone" or "zeroth tone") is:

  • Short and unstressed — barely said
  • No fixed pitch — its actual pitch is influenced by the preceding syllable's tone
  • Not marked with a diacritic — written without any tone mark (just the bare vowel)

Common neutral-tone syllables:

Category Examples
Sentence-final particles 吗 ma (yes/no question), 呢 ne (follow-up question), 了 le (completion/change), 的 de (possessive/attributive), 着 zhe (ongoing), 过 guo (experiential), 吧 ba (suggestion/assumption)
Reduplication of syllables 妈妈 māma (mom), 爸爸 bàba (dad), 哥哥 gēge (older brother), 弟弟 dìdi (younger brother)
Directional complements 上去 shàngqu (go up), 进来 jìnlái (come in)
Common suffixes 们 men (plural for people, if unstressed), 子 zi (noun suffix, in 桌子 zhuōzi, table), 头 tou (noun suffix)

Pitch of neutral tone after each tone:

  • After tone 1: mid-low
  • After tone 2: mid
  • After tone 3: mid-high
  • After tone 4: low

Minimal Pairs

These pairs are commonly confused by English speakers. Drill these specifically:

Pair Pinyin A Char A Meaning Pinyin B Char B Meaning
mā / mǎ mother horse
shū / shú shū book shú ripe; cooked; familiar
mài / mǎi mài to sell mǎi to buy
wèn / wén wèn to ask wén language; culture
jī / jǐ chicken how many; some
lì / lǐ strength inside; mile
shì / shí shì to be shí ten
guó / guò guó country guò to pass; experiential marker
tā / tǎ 他/她 he/she pagoda; tower
jiào / jiāo jiào to call; to be named jiāo to teach

Common Mistakes

  1. Treating tones as optional. Tones are not accent marks or stress — they are phonemic. Dropping them makes you incomprehensible.
  2. Pronouncing the third tone as fully dipping in all contexts. The full dipping shape (214) only occurs in isolation or at the end of an utterance. Before other syllables, the third tone is often just a low tone (21) that never rises.
  3. Not applying tone sandhi for 你好. Saying nǐ hǎo with two actual third tones sounds robotic and unnatural. It's always spoken ní hǎo.
  4. Forgetting 不 changes before 4th tone. 不是 is bú shì, not bù shì.
  5. Ignoring the neutral tone on particles. Sentence-final 吗, 呢, 了, 的 should be unstressed and very short.
