The following critical edition of selected songs by Charles Ives is based primarily on emendations found in two of the composer’s own personal copies of 114 Songs that were discovered in 2012. In the fall of that year, Charles Ives Tyler, the son of the composer’s adopted daughter Edith, sold the family house in West Redding, Connecticut. During the sale Mr. Tyler turned over to the Ives Society several boxes of important documents and paraphernalia that had belonged to his grandfather, all of which were discovered, apparently, during his move-out. These materials were promptly delivered to the Charles Ives Papers at the Yale University Music Library, where they currently reside. The following chapters discuss these materials that were discovered in 2012, and place them in a biographical and musicological context that explains their significance.
