Performance practice is the study of how music was performed over the centuries. This encyclopedia offers entries on composers, musicians/performers, technical terms and musical instruments.

Performance practice is the study of how music was performed over the centuries, both by its originators (the composers and performers who introduced the works) and, later, by revivalists. This first of its kind "Dictionary" offers entries on composers, musicians/performers, technical terms, performance centers, musical instruments, and genres, all aimed at elucidating issues in performance practice. This A-Z guide will help students, scholars, and listeners understand how musical works were originally performed and subsequently changed over the centuries. Compiled by a leading scholar in the field, this work will serve as both a point-of-entry for beginners as well as a roadmap for advanced scholarship in the field.

In twenty-first-century Britain, scientific advice to government is highly organized, integrated across government departments, and led by a chief scientific adviser who reports directly to the prime minister. But at the end of the eighteenth century, when Roland Jackson’s account begins, things were very different. With this book, Jackson turns his attention to the men of science of the day—who derived their knowledge of the natural world from experience, observation, and experiment—focusing on the essential role they played in proffering scientific advice to the state, and the impact of that advice on public policy. At a time that witnessed huge scientific advances and vast industrial development, and as the British state sought to respond to societal, economic, and environmental challenges, practitioners of science, engineering, and medicine were drawn into close involvement with politicians. Jackson explores the contributions of these emerging experts, the motivations behind their involvement, the forces that shaped this new system of advice, and the legacy it left behind. His book provides the first detailed analysis of the provision of scientific, engineering, and medical advice to the nineteenth-century British government, parliament, the civil service, and the military.

The tenth volume of The Correspondence of John Tyndall contains 402 letters covering a two-year period from January 1867 to December 1868. The period centers around the death of Michael Faraday in August 1867. This was a great personal loss for Tyndall, and it led to substantial changes in his professional and personal circumstances, as he succeeded Faraday as superintendent of the house and director of the laboratory at the Royal Institution of Great Britain (RI) and moved into accommodation in the building. He remained there until his resignation in 1887.

The 308 letters in this volume cover a critical period in Tyndall's personal and scientific lives. The volume begins with the difficult ending of his relationship with the Drummond family, disputes about his work in glaciology, and his early seminal work on the absorption of radiant heat by gases. It ends with the start of his championship of Julius Robert Mayer's work on the mechanical equivalent of heat. In between, Tyndall carefully establishes his own priority for his work on radiant heat, and he accepts the position of professor of physics at the Government School of Mines. The lure of the Alps also becomes ever stronger. In this period comes perhaps Tyndall's greatest mountaineering achievement, the first ascent of the Weisshorn, and a remarkable winter visit to Chamonix and the Mer de Glace. As his reputation grows, Tyndall continues to make his way in society. He is elected to the elite Athenaeum Club on January 31, 1860.

Rising from a humble background in rural southern Ireland, John Tyndall became one of the foremost physicists, communicators of science, and polemicists in mid-Victorian Britain. In science, he is known for his important work in meteorology, climate science, magnetism, acoustics, and bacteriology. His discoveries include the physical basis of the warming of the Earth's atmosphere (the basis of the greenhouse effect), and establishing why the sky is blue. But he was also a leading communicator of science, drawing great crowds to his lectures at the Royal Institution, while also playing an active role in the Royal Society. Tyndall moved in the highest social and intellectual circles. A friend of Tennyson and Carlyle, as well as Michael Faraday and Thomas Huxley, Tyndall was one of the most visible advocates of a scientific world view as tensions grew between developing scientific knowledge and theology. He was an active and often controversial commentator, through letters, essays, speeches, and debates, on the scientific, political, and social issues of the day, with strongly stated views on Ireland, religion, race, and the role of women. Widely read in America, his lecture tour there in 1872-73 was a great success. Roland Jackson paints a picture of an individual at the heart of Victorian science and society. He also describes Tyndall's importance as a pioneering mountaineer in what has become known as the Golden Age of Alpinism. Among other feats, Tyndall was the first to traverse the Matterhorn. He presents Tyndall as a complex personality, full of contrasts, with his intense sense of duty, his deep love of poetry, his generosity to friends and his combativeness, his persistent ill-health alongside great physical stamina driving him to his mountaineering feats. Drawing on Tyndall's letters and journals for this first major biography of Tyndall since 1945, Jackson explores the legacy of a man who aroused strong opinions, strong loyalties, and strong enmities throughout his life.
