Voice Training

Voice Technique

Voice technique offers control over the parts responsible for your voice sound, such as the vocal folds, jaw, breathing, and larynx. Training these parts leads to more awareness, confidence, and control over your voice.

read more about vocal technique on our extensive voice training page.

Projection & Dynamics

Technique forms the basis for projection and dynamics. Good projection of your voice, in other words, being audible in every situation, is essential. Projection is not only about volume, so we often treat projection and dynamics together.

read more about projection & volume on our extensive voice training page.

Accent Reduction

Do you have an accent and feel it hinders you in achieving your goals? Then taking lessons in accent reduction is an excellent choice. By training your muscle control in the tongue, lips, and jaw, you can reduce or even completely eliminate your accent.


Improving diction is often overlooked, yet it's of crucial importance. Many think that clear speech requires large movements of the lips, jaw, and tongue. However, the opposite is true: good diction requires subtle movements and minimal adjustment of the lip, jaw, and tongue positions.

read more about diction on our extensive voice training page.

Vocal Health

How do you deal with hoarseness and colds and how do you keep your voice in top condition? This is a frequently asked question, often too late. Therefore, it's important to maintain your voice well. There are two important aspects: voice training and vocal health.

read more about vocal health on our extensive voice training page.

Lesson Duration

A common question is: What is a good length for a voice lesson? The short answer: not shorter than 30 minutes, usually no longer than 45 minutes.

What works for you?

How do you choose a lesson duration that works for you? A lesson shorter than 30 minutes is too short in our opinion for explaining the point of work, creating awareness of the point of work, and learning an exercise. Whether you need a longer lesson is very student-dependent.

A 30-minute lesson

You can learn a lot in a 30-minute lesson. About 40% of all our students choose a 30-minute lesson. When do you choose a longer lesson? It depends on several factors, but here are a few:

A 45-minute lesson:

  • You like to have time to ask questions
  • You find it nice to go through the exercise a bit longer with the teacher


Our rates are based on the level of our teachers. We offer these levels: regular, senior & advanced.

Understanding Your Voice

Estill Voice Training is a model of function, outlining the function of each body part involved in voice production. We believe it to be the most transparent model available, clearly describing both the workings of the voice and effective training methods.

This unique model identifies the structures that produce the voice, as well as the structures in and around the throat (vocal tract) that further shape and modify the sound. This leads to a consciously chosen, reliable, and predictable control over voice production.

Developed by Jo Estill, a singer and scientist, Estill Voice Training divides voice training into two levels. Level one covers exercises for voice control, while level two deals with timbre and voice qualities.

Exercises for Voice Control

In Level One, the voice is divided into 13 trainable components of the body that are responsible for producing sound. This level also offers insights into breath control and delves into the training and effective monitoring of muscle control.

The 13 components are: The vocal folds, the moment of breath to sound, the false vocal folds, larynx, thyroid cartilage, the AES (also known as 'the twanger'), cricoid cartilage, the larynx, the tongue, the soft palate, the jaw, the lips, and your head, neck & torso stabilization.


In the second level, you apply the skills trained in the first level to give your voice 'color', often described as voice qualities, timbres, or vocal characters. By applying the training from level one, you can create one of the six voice qualities proposed by Estill: Speech, Sob, Falsetto, Twang, Belt, and Opera.

These six voice qualities offer each singer an accessible way to become familiar with the idea that you can color your voice as desired. Fortunately, it's not limited to these six voice qualities; you have the freedom to make your voice sound the way you want.

Ultimately, good control of your voice, and understanding how a vocal color is produced, allows you to develop your own sound.
