Among musicologists and serious lovers of music, Wagner's Tristan und Isolde is generally considered the high point of orchestration in the musical tradition of nineteenth-century Europe. It shows in most successful form Wagner's unsurpassed gift for using the instruments of the orchestra, and generations of students have worked with it to learn its technique.Tristan und Isolde also has a remarkable historical position. It was the opera that most of the post-Wagnerians used to build upon, and it was also the opera that the anti-Wagnerians seized upon very frequently for their attacks and for their attempts to move musically away from Wagnerism. Accepted or rejected, it has been the work with which late nineteenth- and early twentieth-century musicians had to come to terms, and much musical history of this period can be understood through it.This edition reproduces the full orchestral score in a clear, modern engraving for easy reading and piano study, with large legible notation. Do not confuse this with a piano rendering; it is a full orchestral score. In addition to its obvious uses for study, this score is also an indispensable associate for anyone listening to recordings. In no other manner can the listener keep full awareness of the incredible orchestral richness of this opera.

"He [Wagner] has been much criticized for this strongly personal statement of a religious subject, which mingles the concepts of sacred and profane love; but in the light of modern knowledge, his insight into the relationship between religious and sexual experience can only seem much in advance of his time."  Encylopaedia BritannicaCompleted in 1882, Parsifal is Wagner's last opera and one of his finest, renowned for its splendid music and glowing orchestration. With its deeply personal treatment of the legend of the Holy Grail, and the subtle intensity and depth of compassion of its treatment of themes of innocence and purity, remorse and sexual renunciation, the opera ranks as one of Wagner's most symbolic, intense, and compassionate works.This Dover edition reproduces every note of this glorious masterpiece from the authoritative C. F. Peters edition, including the list of characters and contents in both German and English. It will be welcomed by musicians, music lovers, opera buffs, and admirers of Wagner as the only complete, inexpensive edition of a 19th-century landmark.

One of the most performed and recorded of Bach's major works, the St. Matthew Passion has been a focal point of concert seasons and festivals around the world for over 150 years. First performed in the late 1720s, it is a drama of epic grandeur, long considered the noblest, most inspired musical treatment of the story of the crucifixion of Christ. Bach set the text, based on two chapters from the Gospel of St. Matthew, using a large ensemble of two choruses, soloists, and two orchestras. The full score is reprinted here from the fine edition prepared by the Bach-Gesellschaft.Although the St. Matthew Passion is often held to be the apotheosis of Lutheran church music, this magnificent oratorio reaches out to its audience in the language, form, and spirit of opera. Richly dramatic and theatrical, following the general form of Baroque opera, it unfolds its deeply moving story in recitatives, ariosos, arias, chorales, and mighty choral movements. This finely produced score offers music lovers the opportunity  at a price far lower than comparable editions  to follow performances score in hand, and to gain a more intimate knowledge of the rich musical textures of this great masterwork.

When the renowned author of the wonderful Oz stories surpasses himself with a full-blown fairy tale, complete with magic wishes, palace life, an evil hag, and a poor boy and girl, we know we are in for something exceptional in storytelling. "In some ways," Baum confided to his son, "Queen Zixi is my best effort." The critic Edward Wagenknecht goes further, terming it flatly one of the best fairy tales ever written by anyone.The master tale-spinner captures suspenseful attention at once with a magic wishing cloak which the fairies decide to give to the first unhappy mortal  man, woman, or child  their emissary chance to meet. At the same time, the King of Noland has died without heir, and the law says the new King shall be the forty-seventh person who happens to pass through the city gates that day. In the neighboring kingdom of Ix, malevolent Queen Zixi, six hundred and eighty-three years old and smug in the secrets of witchcraft, craves that magic cloak with all her evil heart. And that morning, a humble ferryman's son, Bud, happens to be on his way to the city with his pretty sister Fluff ...All who know the enchantment that a real fairy tale can hold for a child will recognize here the ingredients of a spellbinder. Add to them the well-known gifts of the author in creating captivating characters, sparkling fantasy, rich humor, and inventive absurdity, and a true classic of juvenile literature emerges to fascinate both child and parent. An added delight is the inclusion of all 90 of the original illustrations by Frederick Richardson, straight from the pages of St. Nicholas Magazine, where this tale was originally serialized.

The profoundly original ideas introduced by Nobel laureate Max Planck in this endeavor to reconcile the electromagnetic theory of radiation with experimental facts have proved to be of the greatest importance. Few modern introductions to the theory of heat radiation can match this work for precision, care, and attention to details of proof. Although Planck originally intended the book to be simply the connected account of ten years of study, he soon expanded it to a treatise which could serve as an introduction to the study of the entire theory of radiant heat in terms of the recently discovered principle of quantum action. He states his point of view in the introduction: "The hypothesis of quanta ... may be reduced to the simple proposition that the thermodynamic probability of a physical state is a definite integral number, or, what amounts to the same thing, that the entropy of a state has quite a definite positive value, which, as a minimum, becomes zero, while in contrast therewith, the energy may, according to the classical thermodynamics, decrease without limit to minus infinity." Although several other points of fundamental value in thermodynamics are included, the book is basically a rigorous elaboration of this fundamental idea.The treatment starts from the simple known experimental laws of optics and advances, by gradual extension and the addition of the results of electrodynamics and thermodynamics, to the problems of spectral distribution of energy and of reversibility.

"A remarkable work which will remain a document of the first rank for the historian of mechanics."  Louis de BroglieIn this masterful synthesis and summation of the science of mechanics, Rene Dugas, a leading scholar and educator at the famed Ecole Polytechnique in Paris, deals with the evolution of the principles of general mechanics chronologically from their earliest roots in antiquity through the Middle Ages to the revolutionary developments in relativistic mechanics, wave and quantum mechanics of the early 20th century.The present volume is divided into five parts: The first treats of the pioneers in the study of mechanics, from its beginnings up to and including the sixteenth century; the second section discusses the formation of classical mechanics, including the tremendously creative and influential work of Galileo, Huygens and Newton. The third part is devoted to the eighteenth century, in which the organization of mechanics finds its climax in the achievements of Euler, d'Alembert and Lagrange. The fourth part is devoted to classical mechanics after Lagrange. In Part Five, the author undertakes the relativistic revolutions in quantum and wave mechanics.Writing with great clarity and sweep of vision, M. Dugas follows closely the ideas of the great innovators and the texts of their writings. The result is an exceptionally accurate and objective account, especially thorough in its accounts of mechanics in antiquity and the Middle Ages, and the important contributions of Jordanus of Nemore, Jean Buridan, Albert of Saxony, Nicole Oresme, Leonardo da Vinci, and many other key figures.Erudite, comprehensive, replete with penetrating insights, AHistory of Mechanics is an unusually skillful and wide-ranging study that belongs in the library of anyone interested in the history of science.

An Historical and Philosophical Treatment

# data[].attributes.description
In this classic exposition, Ernst Mach presents a detailed account of the experimental and theoretical evolution of our understanding of light phenomena and apparatus. Beginning with the philosophic and physiological speculation arising from early experiments on light and color perception, he proceeds to a thorough examination of the history of diopterics, including the roles of Huyghens, Galileo, Descartes, the Bernoullis, Kepler, and other scientists.Full descriptions of hundreds of experiments and detailed treatments of theory cover Newton's work with color and dispersion, his concept of the periodicity of light, the development of the theory of interference, and the perfection and elaboration of these ideas up until the mid-nineteenth century. A survey of polarization ranges from Bartholinus's paper on double refracting Iceland spar through work by Malus, Brewster, Biot, Arago, to the definitive work of Young and Fresnel. The final third of the book considers the mathematical representation of the properties of light; refinements in the theory of linear, circular, and elliptic polarization; and advanced diffraction experiments, including the theory of the diffraction grating.Students, teachers, and historians of science as well as physicists, engineers, designers of optical systems, and all readers interested in the development and perfection of scientific research will find this volume a stimulating and informative resource.
