Pachelbel's Canon is the name commonly given to a canon by the German Baroque composer Johann Pachelbel in his Canon for 3 violins and basso continuo. It is his most famous composition. It was originally written in the key of D major, but this arrangement has been especially adapted for the more friendly key of Eb Major.
Like most other works by Pachelbel and other pre-1700 composers, the Canon remained forgotten for centuries and was rediscovered only in the 20th century. Several decades after it was first published in 1919 the piece became extremely popular. The piece was particularly prevalent in the pop charts of the 1990s, being sampled and appropriated in numerous commercial hits such as Pet Shop Boys cover of "Go West", Coolio's "C U When U Get There" and Green Day's "Basket Case". It is frequently played at weddings and included on classical music compilations, along with other famous Baroque pieces such as 'Air on the G String'. Although a true canon at the unison in three parts, it also has elements of a chaconne.
