This warm-up does as its name suggests: It wakes up the resonance of your voice. Resonance equals volume without force. This warm-up is also excellent for examining and developing the basic vowel sounds used in singing. Do this warm-up until you notice a difference in the relaxation of the muscles and the resonance of your voice within your mouth and throat.
Your singing voice is produced from the rapid and highly precise actions of small muscles in and around the larynx (voice box). As with any type of demanding physical activity, circulation increases and the muscles swell with blood. Blood supplies all the cells in the body with three essentials for life: oxygen, nutrients and water.
