#1 Warming up prevents vocal injury. If you have ever been to a sporting event you know the first thing that happens is a warm up. There is higher risk for injury if our muscles are not warm and active when we use them. Our vocal cords are just like any other muscle. Injury such as additional/excess strain or tightness in our jaw or neck, early on-set vocal fatigue, or in extreme cases – vocal nodules can be prevented when we warm up our vocal cords properly.
#2 Warming up promotes consistent vocal growth. For dancers, choreography will not stick if only rehearsed once in a blue moon. Similarly, the full benefits of warming up will not be found if only relied on right before a performance. By forming a daily vocal routine, a unique muscle memory is created. Only you can discover, practice, and turn those explorations into muscle memory and expansion. So the more you can revisit your progress, the more growth you’ll see. Which leads me to the third reason.
#3 Warming up prepares you mentally and physically for success. The more familiar you are with your voice, the less likely you are to feel like you’re playing a game of darts when you sing; throwing your notes into the air and hoping one sticks. If you are warming up daily you start noticing certain things about your voice. Where the cracking happens most, what time of day you feel the best, where in your registers (chest, head, pharyngeal) you struggle, versus where a little gunk may need working out. When you warm up your voice you learn more and more about it which allows you to create a sort of monitoring system to find your baseline for singing success!
Never underestimate the power of a good warm up routine. The benefits are immeasurable.
