Let’s talk about your diaphragm

from the old blog Mar 26, 2016

Okay, let’s talk about your diaphragm. I know we voice coaches says things like “breathe with your diaphragm” or “use diaphragmatic breathing,” but to be honest that language is misleading. Why? Because it’s kinda like saying “walk with your feet”…. what else are you supposed to do it with anyway?

Unless your diaphragm is paralyzed (and you’d know if it was!), it’s moving when you breathe. So the question is not whether you’re using it, but how you’re using it. And perhaps that’s not exactly the question either, because your diaphragm functions quite simply. Like any other muscle in the body, the diaphragm is primarily capable of two things: contracting and releasing.

Take a look at this drawing of the diaphragm. A few things to note:

  • The diaphragm is connected peripherally around the base of the ribcage and the front of the spine.
  • In the center of the diaphragm is a central tendon (the whiter part). A tendon is the more dense tissue that generally connects muscle to bone… but in this case it anchors the diaphragm in the center and to the heart above it.
  • The fibers of the diaphragm run primarily vertically.

So…

When your diaphragm gets the signal to contract, the fibers shorten. This brings the two “ends” of the diaphragm together, lowering the central tendon and lifting the base of the ribcage.

When your diaphragm gets the signal to release, it returns to its domed resting position… the ribcage lowers and the center rises.

If you imagine this motion, it’s sort of like the movement of a jellyfish: flattening and expanding, and then returning to its dome shape. You can even try doing that with your hands a few times.

For the diaphragm to move freely, what it really needs is SPACE.

The problem is that the ribcage, the abdominal contents, or muscles in the torso can become rigid and pose resistance to the free movement of the diaphragm. This resistance can lead to issues with breath support and vocal tension. How can this be addressed? By learning to coordinate the movements of the torso so the diaphragm can provide vocal support while moving with as much freedom as possible. In other words, we need to understand how to expend necessary effort with the muscles of the ribcage or abdomen, but use as little excess tension as possible. The irony though, is that as soon as we hear a phrase like “breathe with your diaphragm,” we often start to expend extra effort.

I believe the key to this issue is to keep learning about the diaphragm and the voice and how it all works. When we have a nebulous understanding of how something works, it’s very difficult to make it work more efficiently. However when we’re clear about something works, we can address any needed repairs to the system much more easily. This applies as much to your voice as it does to fixing issues under the hood of your car. So let’s keep researching and asking questions and seeking to understand this beautiful thing called our voice, because how we understand it will affect the way we use and share it!
