Welcome to Unequal Temperaments!
This website and book are devoted to everybody interested in Musical Temperament: performers of all Western musical instruments, singers, keyboard tuners, instrument makers, students and music lovers.
This book deals with the very foundations of Western music: the definition of pitches in musical scales, their acoustical principles, historical development, present-day use, how to tune musical instruments and how to play them and sing in tune. This 4th edition contains 499 pages and 366 figures, and incorporates decades of new findings.
PART ONE provides the acoustical foundations and covers the main temperaments, with a thorough analysis of their musical features. Finally a full HISTORICAL SURVEY guides the musician in the selection of temperament(s) for his/her repertoire.
PART TWO consists of directions for the practice of the different unequal temperaments: keyboard tuning procedures, fret placement in fretted strings, fingering for unfretted strings, intonation for voices, early woodwinds and brass wind instruments, and variable intonation techniques.
PART THREE covers multiple divisions and the analysis of historical sources, including recent research results.
