Answer:
Singing when there's no breath left is a common way of tiring your voice.
Step-by-step explanation:
To breathe properly for singing, you must breathe deep into the bottom portion of your lungs, engaging the diaphragm. This will support your voice. if you don’t do any breathing exercises before singing your lungs would not be able to get as much air. Because breathing exercises help to expand you lungs so you can take in more air and sing longer.
