A 1999 overview of historical performance, surveying issues and suggesting future developments.

This challenging 2002 study examines and ultimately defends the case for historically informed musical performance.

Gillock supplies details about the organ at La Trinité in Paris, the instrument for which most of Messiaen's pieces were imagined.

The seventeenth and eighteenth centuries witnessed the growth of a unique relationship between the French organ and the music written for it. Until recently, however, the roots of this precise musical tradition lay hidden in the sixteenth century. Illuminating these mysteries for the modern audience, Mr. Douglass has traced the development of the French organ from the sixteenth century through the Classical Period (1655-1770).For the first time in English, an explanation is given of the role of mixtures in the plenum of the French instrument of the Classical Period. Because the plenum determines the very character of the organ, and because the mixtures exert the strongest influence upon its sonority, the reader will be able to understand why French composers were writing music for the plenum sharply different from that of their contemporaries in northern Europe. Especially useful is the first complete compilation of known sources of information about French classical organ restriction. Having assimilated the historical facts about the instrument, the reader will be ready to interpret the music of this period on a modern organ.Mr. Douglass is professor organ at the Oberlin College Conservatory of Music. This authoritative study of the French classical organ is a major source for the interpretation of early French organ music. For this new edition, the author has added a chapter on touch in early French organs and its importance for practice. The bibliography has also been extensively revised. Reviews of the previous edition: "The extensive and valuable materials assembled in this study will make it indispensable to both the performer and the scholar of French organ literature."—Almonte C. Howell, Jr., Notes "The only work of its kind in English. . . . Bringing together all of the sources into one volume was alone a task of considerable proportions, and the many conclusions drawn from a careful study of the sources make it a necessary reference for any further study. It should be not only on the shelves but also in the mind of every organ devotee."—Rudolph Kremer, Journal of the American Musicological Society "Douglass has shown us the way that organ studies ought to develop over the next few decades."—Music and Letters

Organ, Volume 3 of the Encyclopedia of Keyboard Instruments, includes articles on the organ family of instruments, including famous players, composers, instrument builders, the construction of the instruments and related terminology. It is the first complete reference on this important family of keyboard instruments that predated the piano. The contributors include major scholars of music and musical instruments from around the world.

Most books dealing with the history of the organ have confined themselves to a single period, area, or even country. This invaluable new work is the first complete survey of the organ ever to have been made in any language. The author firmly bases his interpretations and judgment on extant documents whenever possible, on his practical experience in playing organs all over Europe, and on his close examination of a great variety of instruments at different stages of restoration or transformation. Eight chapters are devoted to the early period and four to the Renaissance. Then individual chapters consider the French classical organ, the organ of Bach, the Spanish baroque organ, the Italian baroque organ, the English organ before 1800, and the northern European organ. The final eight chapters discuss developments in the 19th and 20th centuries. Supplementing the text are a glossary and plates illustrating a full range of organs that are typical of their kind. The eminent English musicologist, organist, and harpsichordist, Peter (Fredric) Williams ranks among the foremost authorities on the organ.
