 The Sousa Archives and Center for American Music in Urbana, Illinois, holds the Harry Partch Estate Archive, 1918–1991, which consists of Partch's personal papers, musical scores, films, tapes and photographs documenting his career as a composer, writer, and producer.It also holds the Music and performing Arts Library Harry Partch Collection, 1914–2007, which consists of books, music, films, personal papers, artifacts and sound recordings collected by the staff of the Music and Performing Arts Library and the University of Illinois School of Music documenting the life and career of Harry Partch, and those associated with him, throughout his career as a composer and writer.Partch's notation is an obstacle, as it mixes a sort of tablature with indications of pitch ratios.
