Over a half a century ago, this work stood as the standard treatise in the field of pipe organ construction. This is volume I of a two volume set, reproduced with care from the 1905 first edition. It opens with the history of the organ and treats various descriptive matters, such as external design and decoration of the organ, acoustical matters in regard to organ pipes, tonal structure and appointment, the compound stops of the organ, etc. Audsley gives an extensive description of all the organ’s components, and set out the differences in structure among church, concert-room, and chamber instruments. This book contains a wealth of information that cannot be found at any other source; the illustrations alone have made it one of the most sought-after books in musical literature.
