 By 1925, Partch was putting his theory into practice by developing paper coverings for violin and viola with fingerings in just intonation, and wrote a string quartet using such tunings.He put his theories in words in May 1928 in the first draft for a book, then called "Exposition of Monophony".He supported himself during this time doing a variety of jobs, including teaching piano, proofreading, and working as a sailor.
