The Pendulograph is a book written by John Andrew in 1881 that explores the concept of sound in a unique way. The book is a series of bi-pendulum writings that delve into the twenty ratios of the musical system. Andrew uses the pendulum as a metaphor for the way in which sound moves through space and time. He examines the relationship between sound and silence, and how they interact with one another. The book is a philosophical exploration of the nature of sound and its relationship to the human experience. It is a fascinating read for anyone interested in music, physics, or philosophy.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
