Editing Dieterich Buxtehude (section)

====Ostinato works====
The three [[ostinato]] bass works Buxtehude composed—two [[chaconne]]s (BuxWV 159–160) and a [[passacaglia]] ([[Passacaglia in D minor, BuxWV 161|BuxWV 161]])—not only represent, along with Pachelbel's six organ chaconnes, a shift from the traditional chaconne style, but are also the first truly developed north German contributions to the development of the genre.<ref name="Snyder"/> They are among Buxtehude's best-known works and have influenced numerous composers after him, most notably Bach (whose organ passacaglia is modeled after Buxtehude's) and [[Johannes Brahms]]. The pieces feature numerous connected sections, with many suspensions, changing meters, and even real modulation (in which the ostinato pattern is transposed into another key).

Some of the [[Prelude (music)|praeludia]] also make use of ostinato models. The praeludium in C major, BuxWV 137, begins with a lengthy pedal solo and concludes not with a postlude of arpeggios and scale runs, but with a comparatively short chaconne built over a three-bar ostinato pattern in the pedal:

The praeludium in G minor, BuxWV 148, in which the ostinato pattern is derived from the subject of one of the fugal sections, also ends in a chaconne. In addition, another praeludium in G minor, BuxWV 149, employs a repeating bass pattern in the beginning.
