“It is a strange fact that the throat is controlled by what happens above it, in the accoustics of the head, through word, vibration and resonance. And stranger still is the realization that the lungs are dominated by the muscular system below them, in waist, abdomen, and pelvis. Head and pelvis are mysteriously connected by coordination of all activities that lie between them.” —Vocal Wisdom: Maxims of Giovanni Battista Lamperti by William Earl Brown (1931).

Giovanni Battista Lamperti, the son of Francesco Lamperti, taught in Dresden, and was the teacher of Marchella Sembrich. His teachings were transmitted by his teaching assistant William Earl Brown in Vocal Wisdom: Maxims of Giovanni Battista Lamperti (1931).
