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 and get the ribcage in an optimal position 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!
