Ursula’s musical treasure chest is filled with abundant experience and broad knowledge. Untiringly she magically creates the appropriate exercise for every voice problem – and before you know it – my voice begins to shine! I am fascinated by her well-founded knowledge about the physiological interrelations of the organs that are relevant to voice production. The small and tiny changes, and not the big ones, are responsible for releasing and invigorating the voice. I profoundly experiended this with IST (Integrative Voice Training).
