The goal of the pilot study in question, carried out by a collaboration between the Science Network Man and Music („SNMM“), Mozarteum University Salzburg, and Tomatis® International (Germany) GmbH („TID“) was to document the effects of the Tomatis® Method on musicians. Using specially modified music (Mozart, Gregorian Chants) the treatment is intended to increase hearing ability, and, consequently, vocal ability of persons undergoing the treatment. The goal was therefore to show a correlation between improved hearing and vocal capability using different analysis methodologies (measurement of psycho-physiological parameters, subjective impressions, audiometry, voice analysis) on students studying voice, and thus to verify whether – and wherever possible provide proof of how – music affected with the Tomatis® Method actually causes such improvements. Additionally, the study was intended to ascertain optimal measurement methods and evaluate the most practical study conditions.
