Taking account of Bach scholarship of the past twenty-five years, the
first two volumes of Peter Williams's classic study of Bach's organ
works are fully revised. This work is a piece-by-piece commentary on
this ever-popular repertoire, demonstrating the music's unique qualities
and how we might hear and play it today. The book follows the order of
the Bach catalog (BWV): beginning with the sonatas, followed by the
"free works" and the chorales, and ending with the doubtful works,
including the "newly discovered chorales" of 1985.
