Years after Walter Piston's death, his students and their students can still take great pride in the enduring vitality of his teaching. By now it is plain that the book is different from what it used to be, but its essential approach and its basic substance remain as they were. The major departure of the fourth edition was the addition of seven new chapters, including four on the complicated subject of harmony after common practice, which had not been discussed in the first three editions. However, then as now, the core of the book remains the exhaustive treatment of common-practice harmony, the subject of most one-year or two-year courses in tonal harmony. In the present edition, the entire text has been carefully revised with a view to clarifying the language and illuminating the essential principles. Wherever possible, the text has been "opened up" to allow the reader to adopt a more leisurely pace through what had been a terse and detailed presentation. The results will also be perceived in the more spacious design of this edition. New exercises have been added to the early chapters as well as some fresh music examples. There is an entirely new chapter on musical texture that serves to clear up many difficult points encountered by the beginning student. Another innovation is the rearrangement of the chapters dealing with harmonic rhythm and the structure of the phrase as well as the inclusion of a short summary of analytical method. This book has long been known as an introductory textbook, but because of its comprehensive range, it also serves as an invaluable reference book. The acquisition of an consummate knowledge of composers' practice the goal of any study of harmony is admittedly an endless assignment. Ars longa, vita brevis, but consolation may be derived from the thought that intellectual and artistic rewards are to be found at all stages along the way."

Year of Decision 1846 tells many fascinating stories of the U.S. explorers who began the western march from the Mississippi to the Pacific, from Canada to the annexation of Texas, California, and the southwest lands from Mexico. It is the penultimate book of a trilogy which includes Across the Wide Missouri (for which DeVoto won both the Pulitzer and Bancroft prizes) and The Course of Empire. DeVoto's narrative covers the expanding Western frontier, the Mormons, the Donner party, Fremont's exploration, the Army of the West, and takes readers into Native American tribal life.

Bernard DeVoto (1897-1955) was a historian, critic, editor, professor, political commentator, and conservationist, and above all a writer of comprehensive skill. As a contributor for more than thirty years to "Harper's" and other magazines, he was known for his forceful opinions. His essays were often brash and opinionated and kept him in the public limelight. One stinging essay even led the FBI to create a file on him. His five serious novels are forgotten today, but his magazine short stories and the well-paid potboilers that he wrote under a pseudonym (John August) subsidized the first of the significant works of American history that brought DeVoto lasting fame. Four of his historical works, all still in print, are "The Year of Decision: 1846," a Book-of-the-Month Club selection in 1943; "Across the Wide Missouri," which won the Pulitzer Prize in history in 1948; 1953 National Book Award-winning "The Course of Empire"; and his popular abridged edition of the "Journals of Lewis and Clark," which also appeared in 1953.
A busy man with a busy life, DeVoto found time to write and answer letters in abundance. In 1933 he received a fan letter from Katharine Sterne, a young woman hospitalized with tuberculosis; his reply touched off an extraordinary eleven-year correspondence. Sterne had graduated with honors from Wellesley College in 1928 and had served as an assistant art critic at the "New York Times" before her illness. Despite her enforced invalidism she maintained an active intellectual life. Sterne and DeVoto wrote to each other until her death in 1944, sometimes in many pages and as often as twice a week, exchanging opinions about life, literature, art, current events, family news, gossip, and their innermost feelings. DeVoto's biographer, Wallace Stegner, states that in these letters DeVoto "expressed himself more intimately than in any other writings." Although their correspondence amounted to more than 868 letters (and is virtually complete on both sides), DeVoto and Sterne never met, both of them doubtless realizing that physical remoteness permitted a psychological proximity that was deeply nourishing.
This volume contains 140 of their letters. They have been selected by DeVoto's son Mark, who has also provided detailed notes clarifying ambiguities and obscure references. Readers will enjoy these letters for their wit and literary flair, but they will also gain insight into the cultural and historical crosscurrents of the 1930s and '40s while taking an intimate and engaging look at a friendship forged entirely through words.
