Which practice is a typical lip exercise in warm-ups for singing?

• A. Lip trills
• B. Lip reading
• C. Lip biting
• D. Lip curling

Answer: (A)

Lip trills are a staple lip exercise in singing warm-ups because they train breath support and vocal coordination while keeping the lips and facial muscles relaxed. When you perform a lip trill, you let a gentle stream of air pass through loosely pressed lips, causing a light buzz or flutter. That buzzing helps connect the breath flowing from the diaphragm to the onset of phonation, making it easier to start and sustain tones with even pressure across pitches. The act of buzzing also releases tension in the lips, cheeks, and jaw, which reduces pinched or tight sounds and supports forward, relaxed resonance. Other options—lip reading, lip biting, or lip curling—do not engage voice production in the same productive way: lip reading is a separate skill, and biting or curling the lips tends to create unnecessary tension. So, lip trills best serve the goal of warming up the voice through relaxed articulation and controlled airflow.
