Harry Partch (1901–1974), American composer, uncle of Virgil Partch
He is best known for his books on American music - Harry Partch: a biography (Yale University Press, 1998) and Ben Johnston: Maximum Clarity and other writings on music (University of Illinois Press, 2006), both of which were recipients of the Deems Taylor Award from ASCAP.
Partch became aware of this possibility when it was pointed out to him by Erv Wilson who also helped him build the instrument.
With the help of Rudolf Steiner’s work, Partch traces the history of these two series, as well as the main other system created by the circle of fifths, and argues that in hidden form the series are balanced out in Bach's harmony.
Partch and his wife died in an auto accident August 10, 1984 on Interstate 5 near Valencia, California.
