The humble lip trill is perhaps one of the most well-known and most versatile singing exercises in the professional vocalist’s toolset. Celebrated by singers in every genre, from classical music to contemporary pop, they are the go-to warm-up exercise for both beginners and experienced vocalists alike.

In this guide, we’ll delve into what makes lip trills (aka Lip Bubbles) so valuable, how to perform them correctly, and when to incorporate them into your vocal routine.

What Are Lip Trills?

Lip trills involve rapidly vibrating or oscillating the lips to create a buzzing sound, often while singing a scale or melody. This exercise is designed to engage your diaphragm and vocal cords, providing you with a controlled and focused way to warm up your voice.

If you’ve ever seen a child make a motorboat sound by blowing air through their lips, you’ve witnessed the basic mechanics of a lip trill. However, when performed as a vocal exercise, lip trills become a sophisticated tool that can help fine-tune your singing technique.

How to Practise Lip Trills

Performing lip trills correctly can take a bit of practice, but once you get the hang of it, they become an invaluable tool in your vocal toolkit. Here’s a step-by-step guide to get you started:

1 Prepare Your Breath

Before you begin, take a deep breath from your diaphragm, not your chest. This provides the support needed to sustain the trill.

2 Position Your Lips

Relax your lips and keep them slightly apart. Imagine you’re about to blow a gentle stream of air through them.

3 Start the Trill

Blow air through your relaxed lips, allowing them to vibrate or ‘trill.’ You should hear a buzzing sound.

4 Sustain the Trill

As you maintain the trill, introduce a pitch by engaging your vocal cords. The aim is to sustain the trill while singing up and down a scale or melody.

5 Variations

Once you’re comfortable, try performing lip trills on different vowel sounds or incorporate them into your favourite songs to challenge yourself.

Why Are Lip Trills Useful?

Lip trills offer a multitude of benefits for singers at all skill levels. Here are some key advantages:

Benefits for Breath Control

Lip trills encourage you to use your diaphragm effectively, helping you to improve your breath control and sustain longer phrases.

Relaxing Facial Muscles

The exercise can relax the tension in your facial muscles, making it easier to hit higher and lower notes without strain.

Smoothing Vocal Transitions

Practising lip trills can help smooth out the transitions between your chest, mix, and head voice, giving you a more seamless vocal range.


Lip trills are not genre-specific and can be incorporated into any singing style, making them a universally useful exercise.

When to Use Lip Trills

Knowing when to incorporate lip trills into your vocal routine can maximise their effectiveness. Here are some optimal times to use this versatile exercise:

As a Warm-Up

Lip trills are a fantastic way to warm up your voice before a singing session, as they engage multiple aspects of vocal technique without causing strain.

Before Challenging Songs

If you’re about to tackle a song that tests the limits of your range or requires smooth transitions between vocal registers, a few minutes of lip trills can prepare your voice for the challenge.

During Recording Sessions

The controlled nature of lip trills makes them an excellent choice for warming up before laying down tracks in the studio.


Right before taking the stage, a quick round of lip trills can relax your vocal cords and help you focus, ensuring you start your performance on the right note.

As a Cool-Down

Though less common, some singers also use lip trills as a cool-down exercise to relax the vocal cords after an intense singing session.

Common Mistakes and How to Avoid Them

Even a seemingly simple exercise like lip trills can be done incorrectly. Here are some pitfalls to watch out for and tips on how to avoid them:

Overdoing It

Lip trills are effective, but like any exercise, they can be overdone. Limit your practice to avoid vocal fatigue.

Incorrect Lip Position

If your lips are too tense or too slack, you won’t get the proper trill. Ensure your lips are relaxed but not floppy.

Breathing Issues

Breathing too shallowly or forcefully can disrupt the trill. Focus on steady, diaphragmatic breathing for optimal results.

Variations and Advanced Techniques

Once you’ve mastered the basics, you might be interested in taking your lip trills to the next level. Here are some variations and advanced techniques to consider:

Adding Scales or Arpeggios

As you become more comfortable with lip trills, try adding scales or arpeggios to make the exercise more challenging.

Combining with Other Vocal Exercises

Lip trills can be combined with other vocal exercises like sirens or humming to create a more comprehensive warm-up routine.

Lip Trills in Different Vocal Registers

Experiment with performing lip trills in different parts of your vocal range, such as your chest, mix, and head voice, to gain greater control over each register.

Unlocking the Benefits of Lip Trills

From mastering breath control to smoothing out vocal transitions, lip trills offer a versatile and effective approach to vocal training. They’re not only a staple in the professional vocalist’s toolkit but a valuable exercise for singers of all levels and across genres.

The versatility and effectiveness of lip trills make them a go-to exercise for singers seeking to refine their technique and expand their vocal capabilities. As with any skill, the key to mastering lip trills lies in consistent, mindful practice.
