This is the most useful book I've ever read on the art and craft of singing, and recommend it highly to professionals and beginners alike. In a different approach to how we're usually taught, Hemsley argues that imagination and focus should be the most important aspects of vocal training. In doing so, he revisits all aspects of voice training, from breathing and "support" (a term he loathes) to colouring and performance, offering alternatives using one's imagination for each.
Reminiscent of Sergius Kagen's "On Singing", Hemsley emphasises preparation of the text and Knowing Thy Score prior to even thinking about singing. Singing ought to start with an urgent impulse to share with the audience a story, which can only be brought about when one has brought the character, music and text to life in one's own head. Again like Kagen, Hemsley spends no time on anatomy or physics, arguing that this can even be detrimental in creating an artist.
A particularly interesting aid is the use of tessitura (which in this case is defined by Hemsley as a single note around which the others are centred). Keeping this note in mind throughout the piece should ensure accuracy of pitch, and better legato.
Overall, Hemsley provides a coherent and common sense framework for a meaningful performance."Testing" his suggestions one by one I found a distinct improvement in my technique and, more importantly, greater enjoyment of the music.
