Liz Caplan draws upon many diverse disciplines in her approach to teaching voice. Her innovative use of physical alignment, exercise and nutrition help to build and maintain a healthy instrument. Yoga, breathing, and relaxation techniques, along with Alexander and Linklater philosophies, are also explored regularly. Vocal exercises, tailored to the individual student, aim to strengthen the larynx and vocal cords as well as releasing the tongue and jaw, yielding increased range and flexibility.
