These “critico-practical” editions by Charles-Marie Widor and Dr. Albert Schweitzer have been a mainstay of organ literature since their publication in 1912. The eight volumes are indexed by the type of composition and offer extensive observations, based on historical evidence and traditional performance, on topics such as registration, ornamentation, and phrasing. A fundamental component of the organist's library.
Volume 6: 77 harmonizations and miscellaneous compositions on 50 well-known chorales. Also, table of Bach's most important ornaments, and specifications of the organs at his disposal.
