Chinese Tones Explained

Tones are the single biggest challenge for English speakers learning Mandarin — and also the single most important thing to get right. In Chinese, the pitch pattern you use when saying a syllable changes its meaning entirely. This guide breaks down all four tones plus the neutral tone with real examples, tone marks, and the critical sandhi rules.

The Four Tones + Neutral Tone

Every syllable in Mandarin carries one of four tones, or occasionally a light neutral tone. Here is the classic example using the syllable “ma”:

First tone (ˉ): Hold your pitch high and steady, like sustaining a musical note. Think of a doctor asking you to say “ahhh.”

Second tone (´): Your pitch rises from middle to high, like the intonation of “What?” in English when you are surprised.

Third tone (ˇ): Your pitch falls low and then rises. In isolation, it has a full dip-and-rise shape. In connected speech, it often just stays low.

Fourth tone (`): Your pitch drops sharply from high to low, like a stern “No!” in English.

Tone Marks in Pinyin

Pinyin uses diacritical marks above vowels to indicate tones. The mark always goes on the main vowel of the syllable:

• ā, á, ǎ, à — tones on “a”
• ō, ó, ǒ, ò — tones on “o”
• ē, é, ě, è — tones on “e”
• ī, í, ǐ, ì — tones on “i”
• ū, ú, ǔ, ù — tones on “u”
• ǖ, ǘ, ǚ, ǜ — tones on “ü”

The rule for placement: if there is an “a” or “e,” the mark goes there. Otherwise, it goes on the last vowel. In “iu” and “ui,” the mark goes on the second vowel.

Third Tone Sandhi — The Essential Rule

When two third tones appear consecutively, the first one changes to a second tone. This is not optional — it happens automatically in all natural Mandarin speech.

With three third tones in a row, the grouping depends on meaning and grammar. For example, 我很好 (wǒ hěn hǎo, “I’m very good”) is grouped as 我 + 很好, so it becomes wó hén hǎo.

Tone Change Rules for 一 and 不

Two common words — 一 (yī, “one”) and 不 (bù, “not”) — change tone based on what follows them:

• 一 is normally first tone (yī), but becomes second tone (yí) before a fourth tone, and fourth tone (yì) before first, second, or third tones.
• 不 is normally fourth tone (bù), but becomes second tone (bú) before another fourth tone: 不是 (bú shì).

Practical Tips for Mastering Tones

Listen before you speak. Spend your first weeks focused on hearing tone differences. Use minimal pair exercises (words that differ only by tone) until you can reliably identify each tone.

Record yourself. Compare your recordings to native speakers. You will catch errors your ear misses in real time.

Use hand gestures. Many teachers use hand movements to trace tone contours — flat for first, rising for second, dipping for third, falling for fourth. Physical movement reinforces the pitch patterns.

Do not skip tones to “learn faster.” Bad tone habits are extremely difficult to fix later. Getting tones right from the start is the single best investment you can make in your Chinese.
