Theory and Practice of Just Intonation: With a View to the Abolition of Temperament is a book written by Thomas Perronet Thompson in 1850. The book explores the concept of just intonation, which is a tuning system based on the natural harmonic series, as opposed to the tempered tuning system that is commonly used in Western music today. Thompson argues that just intonation is a superior tuning system, as it allows for a more pure and harmonious sound. He also advocates for the abolition of temperament, which is the practice of adjusting the tuning of certain intervals in order to make them sound more pleasing to the ear. The book delves into the mathematics and theory behind just intonation, as well as its practical applications in music. Thompson provides examples of how just intonation can be used in various musical contexts, including vocal music, instrumental music, and harmony. Overall, Theory and Practice of Just Intonation is a comprehensive guide to this alternative tuning system, and provides a fascinating look at the history and development of tuning in Western music.As Illustrated By The Description And Use Of The Enharmonic Organ.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
