Question

How exactly do you use your diaphragm to yell?

In: Biology

Answer 1

Take a breath, however you’d normally do so.

Now, try to take a breath so that your upper chest is what’s expanding first when you breathe in–that’s a relatively shallow breath.

Now, try to take a breath so that your lower chest/stomach is what’s expanding first. That’s a deeper breath, using your diaphragm.

Both types of breathing use the diaphragm, but the second way moves a lot more air in and out with more force. So when you’re singing or yelling, breathing like this can help you increase your volume.
