Here are most of the previously unpublished writings of Charles E. Ives: a primary source book on this unique American composer. These Memos, as Ives called them, were on separate leaves and dealt with his music, composition, criticism, autobiography, biography, and many other topics. During his lifetime Ives rearranged them, lent them out, mislaid and tucked them away in books so that, in the late 1940s, only about three-fifths of them were available to his biographer. After his death in 1954, Ives's papers were gradually put in order, and in time most of the remaining leaves came to light. These two batches are here dovetailed into a three-part form by John Kirkpatrick, who has devotedly arranged, edited, and annotated them. Part One, Pretext, sets forth Ives's aims, his views on music, critics and criticism. In part Two, Scrapbook, Ives discusses his music. Part Three, Memories, is devoted to biographical and autobiographical remembrances.
