This collection presents seven works by Lou Harrison for keyboard solo or chamber ensemble spanning more than 50 years. The prefatory essay explores, through the lens of these works, the sources of Harrison"s syncretic style: percussion, East Asian music, gamelan, medieval music, the French baroque, melody, tuning systems, instrument building, and politics. Interwoven biographical material is based on the author"s research for her recent study of Harrison"s life and works, and draws on archival materials and also nearly 75 interviews with Harrison and colleagues who have worked with him during the past half century. The edition was prepared with the full cooperation and assistance of the composer.(Also listed as Volume 31 in Recent Researches in American Music.)
