Harry Partch

Harry Partch was an American composer, music theorist, and creator of musical instruments. He composed using scales of unequal intervals in just intonation, and was one of the first 20thcentury composers in the West to work systematically with microtonal scales. He built custommade instruments in these tunings on which to play his compositions, and described his theory and practice in his book Genesis of a Music .

Partch was born on June 24, 1901, in Oakland, California. His parents were Virgil Franklin Partch and Jennie . The Presbyterian couple were missionaries, and served in China from 1888 to 1893, and again from 1895 to 1900, when they fled the Boxer Rebellion.
