Sing Confidently: 9 Vocal Techniques to Improve Your Voice

Discover the vocal techniques that can bring out your best sound. With the right warm ups, breath control, and tone shaping, you can unlock clearer pitch, smoother vibrato, and a more confident voice.

Here are 9 essential vocal techniques every singer, especially those just starting out, should know.

1. Control Breathing

Breath control is all about learning how to use your air in a steady, controlled way when you sing. When your breath is working for you, your sound becomes clearer, stronger, and much easier to manage. Singing requires intentional breathing, so it helps to stay aware of how you inhale and release your air as you go.
  • Stand or sit up straight, with your chest lifted and shoulders relaxed
  • Position your tongue, mouth, and jaw for the next vowel you’re going to sing.
  • Relax your throat and open your vocal folds.
  • Breathe in silently and smoothly, without moving too much.
  • Expand your rib cage and abdomen as you inhale.
  • Use abdominal and intercostal muscles to exhale. Try to keep your abdomen and ribs engaged.

2. Reduce Tension and Relax

Some muscle engagement is normal when you sing, but too much tension can get in the way. The most common tight spots are the neck, jaw, tongue, lips, shoulders, and even the legs.

To ease tension, take a moment to scan your body from your feet up to your head. Gently relax each area as you go, giving extra attention to your jaw, lips, and neck. This helps you sing more comfortably and with less strain.

Many singers also open their mouths too wide to create more resonance, which often leads to jaw tension. To help with this, try sustaining an “ah” sound while gently massaging your jaw joints with your fingers.

You can also watch yourself in a mirror and move your jaw slowly up and down within a smaller, comfortable range. Focus on releasing the tension in the back of your jaw as you open it so you can feel what relaxed movement really feels like.

3. Make a Good Singing Posture

When your body is in a good posture, it allows air to flow easily in and out of your lungs, which helps to create a clear and stable sound.

To make a good posture, keep your spine straight, your chest lifted, and your shoulders relaxed. Your face should be forward and avoid tilting your head up or down when trying to reach high or low notes. Also, avoid making big movements, such as swaying your arms or raising your chin and eyebrows too much.

4. Always Warm Up Before You Sing

Vocal warm-ups are a set of exercises that prepare your body and voice for singing. Warming up can improve your singing posture and make your body feel more comfortable, which also leads to preventing injuries and improving your tone quality. 

There are many different warm-up exercises you can do, such as humming, using the yawn-sigh technique, lip trills, scales, and arpeggios. You can find these exercises online or ask your singing teacher to guide you through them and give tips on how to warm up effectively.

5. Understand the Resonance

When we sing, our voice bounces and gets amplified by different parts of our throat, mouth, and nose. By using these different areas, we can create a clear and consistent sound with better pitch and more range.

For example, if you raise or lower the “soft palate” at the back of your mouth, you can create nasal resonance. You can try breathing out through your nose to feel the soft palate lowering, and then imagine you’re surprised and take a sudden breath through your mouth to feel it being raised.

6. The Vibrato Technique

Vibrato is a technique where a singer changes the pitch of their voice slightly to create a vibration. It adds expressiveness and improves the quality of the performance. Most singing styles use vibrato to some degree, but the amount and duration of vibrato can vary. Classical singers typically use a moderate vibrato throughout a phrase, while modern pop artists tend to use vibrato on the final note or at the end of a phrase.

If you’re a beginner, try to avoid making an artificial vibrato. The most effective way to master the correct vibrato technique is by working with a professional voice teacher.

7. Keep Your Vocal Cords Healthy

Here are some helpful and easy tips to keep your voice in good shape:

Stay hydrated

You should stay hydrated by drinking plenty of water. When your body is dehydrated, your vocal cords can become dry and swollen, which can lead to vocal strain and damage.

Avoid smoking and excessive alcohol consumption

These can easily irritate your vocal cords and cause long-term damage.

Rest and avoid overusing the voice

Your voice can become tired and strained if you are tired or not getting enough sleep. Make sure to get enough rest and take breaks during long practice sessions. When you’re preparing for a performance, try to keep yelling and excessive talking to a minimum.

8. Learn How to Dictate Words in Singing

When it comes to singing, it’s important to be able to clearly communicate the lyrics to your audience. Good diction involves pronouncing both consonants and vowels properly. You can improve your diction by focusing on the shape of your mouth and recording yourself singing to listen to it later for feedback from your instructor.

9. Practice Intonation

Singing in tune, or in other words, intonation, is a vocal technique that requires accurate pitch and musical intervals. You can improve your intonation by doing vocal warm-ups and matching pitch with a piano or another instrument. It’s also helpful to actively listen to recordings of skilled singers to develop a better ear for intonation.
