Recently I've been thinking a lot about posture. I used to think posture was important only insofar as it affects your breathing and support, but try this experiment to see how fundamental the effects of posture can be to the voice source in singing:
- Stand in a normal position, the way you are used to.
- Start singing a nice, rich "ah" vowel, at a comfortably full, sustained volume.
- Without stopping the "ah", jut your chin forward and out as far as it will go.
- Now pull it back again, even farther back than your starting position if you can.
- Observe what happens to your sound.
If my explanation was clear enough and you were able to do this experiment, you will have noticed a perceptible change in both the resonance of your tone and the color of your vowel. Jutting the chin forward robs the voice of presence and ring, and modifies your vowel towards "uh". This is because it puts an upward strain on your larynx, causing it to rise (or, at the very least, to make you work hard to keep it in a lower position, resulting in tension.)
This exercise alone is enough to convince most students (and myself) of the importance of posture. At first, posture corrections are necessarily conscious, and somewhat stiff. With time, you begin adjusting your posture reflexively, in response to the sound itself.
To establish a good singing posture, check the following:
- Bring your shoulders back, expanding your chest.
- Keep your head high and straight above the shoulders. Avoid jutting the chin or tilting your head up. If anything, you may feel that your are tilting the head slightly forward and/or pulling it back at the chin, though avoid doing either of these in excess, as well.
- When breathing and singing, the shoulders do not rise. The chest stays expanded. As a consequence of these two principles, you will feel your breathing lower in your abdomen and across your back. It is not necessary to exaggerate these outward sensations, but welcome them.
- At the upper extremes of your voice, you may need to consciously increase the core muscles in your abdomen to generate the pressure necessary for these notes. An excellent post about what elite breath support feels like can be found in the post Appoggio: An Actual Support System on Dr. LaFond's blog, Kashu-do: The Way of the Singer.
I think of the expanded chest, relaxed shoulders, and straight neck as the "frame" within which all singing occurs. Once this frame is established, you can move around on stage, sit, stand, or lie down, sing while gesturing with your arms, etc. But the frame is the fundamental core of technique. Without it there can be no efficiency in the vocal source and tract as well as no proper breath support.
