Perhaps the most important composer of organ music before Bach, Dietrich Buxtehude (c. 1637-1707) was one of the most influential musicians in northern Europe. His brilliance as a performer is said to have inspired the young Johann Sebastian Bach to walk 200 miles from Arnstadt to Lübeck to hear his performances. The most important of Buxtehude's instrumental compositions were for organ, and this volume presents virtually all of the composer's organ works -- 78 toccatas, preludes, chorale variations, chorale fantasias, chorale preludes, fugues, canzonettas, chaconnes, and other works -- reprinted directly from the definitive Breitkopf & Härtel edition by Philipp Spitta and Max Seiffert. Professional and amateur organists, musicians, and music lovers will welcome the opportunity to study and perform these masterful compositions -- conveniently reprinted in this attractive, inexpensive, and authoritative edition.
