The Deal with the Diaphragm, Pt. 2

The Deal with the Diaphragm, Pt 2

In the first post we looked at the diaphragm and its role in inhalation – It is the primary muscle involved in the lifting of the ribs and the expansion of the abdomen upon inhalation. To be extra clear, it is always involved in breathing – there is no such thing as a non-diaphragmatic breath. It is just a matter of how efficiently it works. When you are a singer you need it to be very efficient, and the way we use the other muscles of inhalation and exhalation allows the diaphragm to function efficiently.

When we sing we need to slow down the rate at which air is expelled so it matches the needed amount to set the vocal folds in motion at the appropriate pitch and gives you the ability to sing through a phrase. We can’t do that with the diaphragm because we have no direct control over it.

We accomplish this by engaging the accessory muscles of exhalation. (When you aren’t singing you can slow the breath down by pursing the lips on exhale or by using an ujjayi breath). The abdominal muscle that has the most direct relationship to the diaphragm is the transverse abdominus, the deepest layer of belly muscle, because it attaches to the body at many of the same points that the diaphragm does. We often refer to muscles in pairs as antagonists (think bicep and tricep in your arm). The transverse abdominus is the antagonist of the diaphragm. The other accessory muscles and their antagonists include the obliques (belly) and the costals (ribs), but we’re looking most closely at the transverse abdominus here.

If the diaphragm returns to its resting position quickly, you get a big burst of air that will either make your sound breathy, out of tune or more difficult to create than it should be. So, when we slow its return down by engaging the other muscles of the abdomen and back, especially the transverse abdominus, you create what is often referred to as ‘support’.

So, how do you know you are engaging the transverse abdominus muscle?

Try This:

Lie down or sit in a comfortable, well aligned manner. Place your hand just above your pubic bone on your low belly.

Exhale as though you are breathing out through a straw, continuing until you feel as though you are out of air. Like, really, really out of air.

While exhaling pay attention to where you feel muscle engagement – hopefully you feel it beneath your hand in the lowest part of your belly, almost as low as where the pubic bone is. That muscle engagement is the transverse abdominus muscle and that level of engagement is only for demonstration purposes to find it. We use it more subtly when we sing, not wanting to have any visible motion of the belly up and in as we sing through a phrase. If you aren’t sure if you engage it when you sing, try vocalizing on the sounds v, m, n, or the ng sound from the word sing with your fingers pressed into your softened belly. Those sounds are good triggers to engage the muscle and you’ll feel it press against your fingers when you vocalize.

Enjoy!

The Deal with the Diaphragm, Pt 1

“What do you know about breathing for singing?”

This is one of the questions asked of students in my voice studio at their first lesson. My least favorite, yet most common response is, “well, I know you breathe from the diaphragm,” uttered as they hold their hand vaguely over their abdominal area.

If that is their answer we go no further.

The diaphragm, for those of you who don’t know, is an involuntary muscle. That means we have no direct control over it. We cannot make it do anything. At all. When not engaged it rests at the bottom of the rib cage. When activated it contracts and pulls and aides with inhalation.

Because it is an involuntary muscle, we do not ‘breathe from the diaphragm’ anymore than we breathe from our stomach. We breathe through our mouth or nose, down the trachea and into the lungs. Breathing occurs through an interplay of muscles, including the diaphragm, that pull on lung tissue, create negative pressure and allow air to rush in (a very boiled down explanation with apologies to those who do anatomical things for a living and would give a more complex, in depth explanation).

What we want is a diaphragm that is free to descend to its maximum position, allowing the bottom portion of our lungs, where the bulk of our lung tissue lives, to fill with air, giving us the best shot at singing long phrases.

What we need is a set of abdominal muscles flexible enough to allow the contents of the abdominal area (stomach, liver, spleen etc) to move forward when the diaphragm encounters them. Because the diaphragm inserts on itself in a central tendon,  its flexibility is also partly dependent on the flexibility of the hips and spine. (Working on flexibility while building strength is one of the many reasons why yoga can be helpful for singers.)

When teachers and conductors and the like tell students “Breathe from your diaphragm!” what they mean is release your abdominal muscles so the diaphragm is free to descend on inhalation.  We ‘feel a low breath’ because there is expansion in the belly as things move around.

The way the diaphragm is involved with exhalation and how it is paired with its antagonist muscles in the abdomen to provide the foundation for a supported sound is for another post.

Go forth and sing, but know that you aren’t controlling your diaphragm as much as you might think you are!
