Margaret Watts-Hughes booklet "The Eidophone Voice Figures" is testimony to her inventive and creative genius.
In 47 pages she describes how she created an amazing range of [cymatic] forms 125 years ago, long before Hans Jenny explored similar techniques for making sound and vibration visible. If you are a student of cymatics or investigating new ways of working with sound, this is a MUST read.
