Vocal Technique – Part 1


 The Voice

Vocal Pedagogy

In this post, I will teach you about the science that is behind the voice. Hopefully, you’ll be able to come away from this article with knowledge on strain, resonance, pitch, support, etc.

In a nutshell, vocal pedagogy (vocal technique) is the study of the science in the field of singing. Since vocal technique is directly related to science, it is a good way to use it to judge a vocalist or a performance accurately and objectively. Vocal pedagogy consists of the following:

  • Physiology Of Singing
  • Breathing In Singing
  • Posture
  • Phonation
  • Intonation
  • Resonace
  • Tone Production
  • Vibrato
  • Vocal Articulations
  • Vocal Diction
  • Vocal Registrations
  • Vocal Health
  • Vocal Styles
  • Voice Classifications
  • Coloratura

Physiology Of Singing

Physiology of singing refers to the body parts involved in the sound production. There are three components:

Vibrator: Vocal cords/folds located inside the larynx fully come in contact and vibrate together in order to make vocal sounds.

Activator: The breath/air pressure from our lungs and various muscles of our body is responsible for the vibrations in order to make sounds.

Resonator: The pharynx amplifies the vibrations from the vocal cords creating a resonant/reverberating sound.

Breathing In Singing

Breathing is the fundamental core when it comes to singing. You have to breathe to sing, and not just any breathing, you need good breathing to be able to sing well.

So how should one breathe whilst singing?

Firstly, one should inhale from their diaphragm, which allows more air to enter the body. A good way to determine whether or not a vocalist is breathing their diaphragm is to observe the movement of their shoulders. If a vocalist’s shoulders are moving upwards during inhalation, whilst singing, then the singer is not breathing from their diaphragm. One’s shoulders should always remain still and relaxed whilst singing.

During inhalation, one’s diaphragm expands, contracts, and goes downwards, whereas during exhalation the diaphragm slowly relaxes into its original position by moving upwards.

Additionally, one should avoid breathing out too quickly. This is because if one pushes the air out whilst one sings, an airy and weak tone will be created. A vocalist must breathe out as slowly as they can so that they have enough air in the vocal cords to execute complex vocal lines and/or notes with ease. If a vocalist doesn’t have control over the amount of air they exhale while vocalizing, they will most likely strain (and in extreme cases will be unable to produce a line of connected notes — see Park Bom). This is why supporting one’s voice is extremely important, as it distinguishes a skilled singer from an unskilled singer.

The less air you use, the more powerful the singer’s voice will sound whilst singing. To achieve this, one should practice contracting the diaphragmatic, abdominal, and side muscles to have full control over the air that you breathe out so exhalation can happen as slowly as possible.

The whole point of this is to create an optimal and healthy sound, because good breathing equals a good sound output.

In summary, the two integral parts of breathing in singing are:

Breath Support: The interactions between various muscles in order to control the air used to vibrate the vocal folds.

Breath Control: The regulation and coordination of the airflow above the vocal cords.

To avoid confusion, remember that Breath Support happens underneath the vocal folds and relates to the movement of the muscles, namely the diaphragm; whereas Breath Control happens above the vocal cords and has to do with the steadiness, coordination, and regulation of the airflow in the body. Proper tone production, vocal power, the ability to execute very low and high notes properly, and belting properly all have to do with breath support. Sustaining notes (especially harder ones), handling complex vocal lines, executing vocal runs/melismas properly, being able to play with vocal dynamics (levels of volume), being able to produce a proper vibrato, and singing in either legato or staccato properly all relate to breath control.

Finally, breath support and breath control are related to each other because without proper breath support it would be hard to have proper breath control.


It is very important for the singer to not just pay attention to how they breathe, but to also pay attention to their posture. Great breath control is useless if your posture sucks because the air won’t be flowing in the proper areas.

This is an example of bad posture whilst singing:

A singer’s shoulders should always be relaxed and down; if they are moving up and down as the singer breathes it means that they don’t have enough air to support their notes correctly. This creates tension in the whole of the upper body that leads to strain.

The singer must not slouch. The shoulders have to be kept back and in a straight line. Slouching prevents the airflow from circulating around the body properly, leading to tension in the vocal cords, which causes strain. This is due to the slouch causing the muscles used to support the voice being folded over. No matter if the singer is standing or sitting, they must keep their shoulders back and in a straight line.

The jaw must be kept relaxed as well. When the jaw is relaxed, the tongue stays out of the throat, keeping the larynx neutral. Pushing the jaw forward — a fail attempt at trying to create more volume — causes the tongue to be pushed back, which causes the larynx to be pushed down, thus creating a froggy-ish and throaty sound.

The larynx should always be relaxed and in a neutral position. If your larynx is too high or too low, it means that you’re breathing incorrectly. If a singer’s larynx is not neutral, they will strain.

Last, but not least, the neck and head position. The head should be held up.

The head should be held up, but not too high. The head’s ideal position is when the jaw is a little over the horizontal, as this allows the throat to open whilst singing. Kyuhyun is a great example of someone who knows how to hold their head whilst singing. Unfortunately, the same cannot be said for Junsu.

Lifting your head higher to sing high notes, or putting it down to sing low notes, does not help whatsoever. In fact, it creates tension in the neck that will prevent the throat from opening, thus causing strain.

  1. Are you supposed to sing with an even mix all the way up to your highest belt? Or lighten as you get higher?

    Also do you think singers like Ailee and Jojo sing with such chesty mixes bc they were taught to sing like that,or because they choose to?


    1. I personally believe that your mix should be flexible, you should be able to choose when to be chesty, heady or balanced but as you get higher there must be a natural need to lighten up ever so slightly to allow the sound to move up.
      I think that they do it as a habit for the most part without being aware.


  2. So I’ve heard it used in some songs & was wondering if you guys have an opinon on the ‘growl technique/style’? Is there a specific &/or healthy way to produce it? Cause it sounds cool but also like it would hurt your throat if not done properly.


    1. There is a healthy way to do it and an unhealthy way, but I’m not sure how it works. If you do it harshly with your vocal cords it’s damaging but if you use the false vocal folds instead it’s fine I think but I could be wrong.


      1. Interesting! Thanks! (Heard some people say it’s kind of like clearing your throat while singing but wasn’t sure if that was all that there was to it.) Hope you guys can keep up the awesome work you’ve got on this website too! 😊

    1. Hi Carren. Make sure sure please that if you ask me about your own singing and ask me if you’ve improved after last sending an audio 6 months ago, you provide a link to the older audio that I listened of you so that I can better tell you if there’s improvement in your technique. You sound less shy from what I can hear, I am listening by comparing to what I said before and the last audios. I still think it’s better to focus on a song in a language you speak and this song is a bit demanding on the higher parts for you, so you start losing stamina cause you’re not preserving your air enough. How have you practiced is my question? If you’re asking about improvement, the method that you used to practice is vital to understand how to improve.


      1. I’m so sorry! Here is the link: https://www.dropbox.com/s/5jt45qc79pp35qe/Listen.mp3?dl=0
        I will sing in a language i’m comfortable in next time haha
        I practiced the bright smiley sound so my larynx doesn’t get lowered as much
        I also practiced the diaphragm by counting and holding the breath and such
        I tried to open my mouth more so I can project better
        I don’t understand how to connect my voice more so I just try to hold it longer..?
        Tbh I haven’t been able to practise much because I don’t have time …
        Sorry for the trouble Ahmin and thank you for the reply 🙂
