Mattia is a professional singer, songwriter and vocal coach. He’s perfected a technique that involves placing his voice in different parts of his body to change the sound and quality of his performance. But whether the performance is musical like Mattia’s, in the visual arts, writing or even business, it all comes down to communication—a subject about which there is much to learn in The Scientology Handbook.
