This instructive book on "music without instruments" was, at the time of its publication, the only comprehensive practical work of its kind in the world. It describes the beginnings of what we now know as 'radiophonic' work, and offers a fascinating insight into the early methods of creating atmospheric soundtracks for both film and television.
The author, F. C. Judd, was an Associate of the Institute of Engineering, and known to students who attended Summer Music Schools at Dartington Hall. Described as 'one of the small handful of acknowledged pioneers in the making of "new music" and its application to film and television, his writing style is clear and accessible, and the diagrams also neat and comprehensible.
The book is in very good condition, protected by a (clipped) dustjacket which has suffered only minor wear and tear (one tear with some loss at the top back R/H edge, and some other minor chips). Bound in light grey cloth, with gilt title etc on the spine, it shows almost no signs of shelf wear. The binding is firm, all pages are clean, though lightly browned, and the only defect is some browning to the final blank page before the rear free endpaper (see photo).
