Charles Ives' massive Concord Sonata, his second sonata for piano, named after the town of Concord in Massachusetts, is central to his output and clearly reflects his aesthetic perspective. Geoffrey Block's wide-ranging account of the work thus provides an ideal introduction to this fascinating composer. This handbook discusses the Sonata's reception history and its compositional genesis, as well as providing a detailed account of the work's thematic content, its use of borrowed material, and the degree to which the program is influenced by the Concord Transcendentalists.
