Which vocal exercise helps to reduce tension in the voice?

Humming is an effective vocal exercise for reducing tension in the voice due to its calming nature and focus on resonance. When you hum, you engage the vocal cords gently without straining them, allowing for a warm-up that promotes relaxation in both the voice and the surrounding vocal muscles. This exercise encourages breath control and helps to minimize tension since it produces sound without the harshness of full vocalization. The gentle vibrations created during humming can also soothe the larynx, making it an excellent choice for singers seeking to alleviate stress on their vocal apparatus.

The other options do not serve the same purpose. Shouting can lead to vocal strain and tension, as it requires the vocal cords to work harder against increased airflow and pressure. Speaking in a soft voice, while gentler than shouting, might not offer the same level of relaxation and resonance needed to properly warm up the voice. Reading music silently does not engage the vocal cords or address any vocal tension, as it lacks the necessary vocal production and breath management needed for reducing tension. Humming stands out as the most beneficial practice for achieving a relaxed vocal state.
