This book contains a method for the correct placing of the voice. Made especially for nonprofessional and professional singers alike, the method is written by the american singer Julie Massino, one of the best voice coaches in the world and is based on mastering the voicing of the five vowels: OY / O / A / E / I.
A very difficult project in terms of art-direction, not only because all schematics and gestures had to be accurately depicted and easily understood but also because the method itself is very complex to be given via a book.
