This is an excellent and rare book - a practical voice book that is anatomically correct and well-researched but written in a wholly approachable manner by a sensitive and highly experienced practitioner. It can be difficult to work on your own voice via a book but Barbara Houseman offers a step-by-step guide accompanied by helpful little illustrations. The book contains a trouble-shooting section and warmups and warmdowns for different situations. These are timed and cross-referenced back to the main text. The lay-out is unusual - clear and fun with little boxes adding information or exercises. I am finding it immensely helpful and interesting. I teach too and it is helping with my own voice use and understanding of thevoice. I imagine it would be useful to anyone who uses their voice in pursuit of their work - teachers, politicians, interviewers, business people etc as well as being invaluable to actors and performers. I highly recommend it.
