This book records the results of certain clairvoyant investigations carried out by Mr. Geoffrey Hodson on the effect produced by music upon adjacent matter of the superphysical world.

Eight compositions, including Handel, Bach, Mozart, Haydn and Wagner were studied and the results are recorded here in words and colour.

Mr Hodson"s observation arising from his clairvoyant research were carefully taken down while each performance was proceeding , and to these descriptions pictures were produced by artists later.

The music was under the guidance of Dr Gordon Kingsley, of Beverley Hills Church in Hollywood, California, and he has provided notes on the compositions.

Also included is a study of the responses of physical substances to various vibrations, carried out by the Swiss scientist and artist Dr Hans Jenny, published here by permission of the author and the editor of THE UNESCO COURIER, 1969, in which it appeared.
