What actually happens inside the body when a person is speaking and singing? This question is of great importance for anyone who makes conscious use of his or her voice, since the vocal processes inside the body normally cannot be seen. With the help of modern ivestigative techniques from high-tech medicine this DVD demonstrates - for the first time ever - exactly what takes place in the human body when a person is speaking and singing. In 99 film clips the movements of the respiratory system, the larynx, and the vocal tract can be observed during various types of voice production. In addition, the films and animated sequences explain the most important organ systems involved in forming the voice. The material provides interesting insights for every singer, voice teacher, music teacher, physician or voice researcher. The HELBLING Media App gives access to all Films for the DVD-ROM "The voice".
