Mandarin Tones: Pitch Contours

What Are Tones?

In a non-tonal language like English, we use pitch changes for intonation—to express emotion or to signal a question versus a statement. For example, the pitch of your voice rises at the end of "You're coming?" but falls at the end of "You're coming." In both cases, the word "coming" still refers to the same action.

In Mandarin, pitch is used differently. It's a core part of the word itself. A change in pitch, or tone, creates a completely different word.

To understand this better, please read the following brief introduction.

As you read, the key takeaway is that getting the tone wrong isn't just a matter of having a slight accent; it's like saying "horse" when you meant to say "mother." This is why we are dedicating our first few lessons to mastering them.

Visualizing the Four Tones

To talk about tones, linguists and teachers use a five-point scale, where 1 represents the lowest pitch in your natural vocal range and 5 represents the highest.

Here is a standard diagram showing the pitch contour of the four main tones. Each tone has a number, a name, a diacritical mark used in pinyin writing (which we'll cover later), and a shape.

Now, let's break down each tone one by one.

The Standard Description of the Four Tones

We'll start with the classic, standard way each tone is taught. This video provides clear demonstrations of each tone's sound and shape.

Based on the video and the chart, here is a summary of each tone's pitch contour:

1. First Tone (ā): High and Level

   • Contour: Starts high and stays high. It's flat and sustained, like holding a single, high musical note. (Pitch: 5-5)
   • Analogy: The sound you might make for a dentist saying "say ahhh."

2. Second Tone (á): Rising

   • Contour: Starts from a mid-range pitch and rises to the top. (Pitch: 3-5)
   • Analogy: The upward inflection you use in English when asking a question like "What?" or "Huh?".

3. Third Tone (ǎ): Dipping

   • Contour: Starts mid-low, dips to the bottom of your vocal range, and then rises again. This is the most complex contour. (Pitch: 2-1-4)
   • Analogy: There isn't a perfect English equivalent, but you can think of it as a "bouncing" sound.

4. Fourth Tone (à): Falling

   • Contour: Starts high and falls sharply and quickly to the bottom. (Pitch: 5-1)
   • Analogy: The sound of a curt command, like saying "No!" or "Stop!".

A More Nuanced, Practical Description

The standard descriptions are a good starting point, but they don't always reflect how native speakers actually talk. Your preference for an analytical approach will be well-served by understanding these nuances from the beginning.

This next video, from a native Mandarin speaker with a PhD in Chinese Linguistics, reveals some "secrets" about the tones that will make your pronunciation sound more natural.

Let's update our understanding with these crucial insights:

• Refined First Tone (ā): Instead of straining to make it extremely high (5-5), think of it as a natural, mid-high, flat tone. It should feel relaxed, not forced.
• Refined Third Tone (ǎ): This is a critical point. While the "full dip" (2-1-4) is the dictionary form, in most real-world situations, the third tone is simply a low, creaky tone that dips and stays low (2-1). The final rise is usually omitted unless the third tone is said in isolation or at the end of a phrase. For now, thinking of it as a "low tone" is a very effective strategy.

Beyond Pitch: Duration and Intensity

To deepen your analytical understanding, there's one more layer to tones. They don't just differ in pitch; they also have distinct properties of duration (how long they last) and intensity (volume). Native speakers unconsciously use these cues to identify tones, even if the pitch information is unclear.

Here’s a summary of those additional properties:

This multi-faceted view—pitch, duration, and intensity—gives you a powerful analytical framework for both listening to and, eventually, producing the tones accurately.

Conclusion

In this lesson, we have laid the essential groundwork for understanding Mandarin tones. You have learned not only the standard descriptions but also the practical nuances that will help you develop a more authentic accent.

Here are the key takeaways:

• Tones are essential for meaning in Mandarin, distinguishing words that otherwise have the same pronunciation.
• The four main tones have distinct pitch contours:
  • 1st Tone (ā): A steady, mid-high pitch.
  • 2nd Tone (á): A rising pitch, like asking a question.
  • 3rd Tone (ǎ): A low, creaky pitch. It is the longest and quietest tone.
  • 4th Tone (à): A sharp, falling pitch. It is the shortest and starts loud.
• Thinking of the third tone as simply a "low tone" is a powerful and practical simplification for beginners.

In our next lesson, we will move from theory to practice. You will learn to produce these four tones on simple syllables and begin training your ear to tell them apart. You'll be taking your first steps toward actually speaking and hearing Mandarin.
