This is the famous Canon D major, performed with the original instrumentation: 3 violins, cello and harpsichord. The Canon in D major (full German title: Kanon und Gigue in D-Dur für drei Violinen und Basso Continuo) is the composer Johann Pachelbel’s most famous piece. The Canon in D is the only canon that Pachelbel wrote. The music can be found on many classical CDs, along with works such as the Air on G string (BWV 1068) by Johann Sebastian Bach. The work was written by Pachelbel about 1680 as a chamber music piece for three violins and basso continuo. Various transcriptions of this piece have since been made by others for other musical instruments, such as organ and piano.
The piece also includes a Gigue, but this one is played much less often.
Best known for its chord progression, Pachelbel’s Canon has become one of the most popular classical pieces of music and is used almost as often as the basis for pop songs.
