The concept of brain hemisphere dominance serves as the basis for many educational learning theories. The dominant brain hemisphere guides the learning process, but both hemispheres are necessary for true learning to take place. This treatise outlines and analyzes the dominance factor, a learning theory developed by Dr. Carla Hannaford, which focuses on the impact of the student's dominant hemisphere, eye, ear, hand, and foot when learning new material and in times of stress. The methods for establishing the dominance profile are defined, and the dominance profile is then evaluated for its meaning and application to the voice studio. In applying the dominance profile of the teacher and student to the voice lesson and student's practice time, the act of singing becomes a whole-brain activity and learning is more efficient and effective.
