Name one common vocal warm-up exercise.

Lip trills are a common vocal warm-up exercise because they effectively help in relaxing the vocal cords and improving airflow. When singers perform lip trills, they create a sound while blowing air through pursed lips, which produces a buzzing sound. This technique encourages proper breath support and helps to engage the diaphragm, promoting a more relaxed state for the voice.

Additionally, lip trills can be done across different pitches, which is beneficial for developing vocal range and flexibility. They also reduce strain on the vocal folds, making it a safe way to warm up the voice before singing or performing. This exercise is particularly popular among singers because it primes the vocal mechanism for production without the tension that other vocal exercises might introduce.
