Just like any other muscle in your body, your vocal cords and surrounding muscles benefit from warm-up exercises to prepare them for performance. Warming up your voice before singing or speaking can help prevent strain, improve flexibility, and enhance overall vocal quality. One effective warm-up exercise is lip trills, which involve blowing air through slightly pursed lips to create a buzzing sound. This exercise helps relax and stretch the muscles around your mouth and vocal cords, while also promoting airflow and resonance. To perform lip trills, start by taking a deep breath and then exhaling through your lips, allowing them to vibrate together as you move up and down in pitch. Repeat this exercise several times, focusing on maintaining a relaxed and steady airflow.
