crab canon

A crab canon (also known by the Latin form of the name, canon cancrizans; as well as retrograde canon, canon per recte et retro or canon per rectus et inversus) is an arrangement of two musical lines that are complementary and backward.

Such a canon is also called a round or, in medieval Latin terminology, a rota. Sumer is icumen in is one example of a piece designated rota.

In the 18th century, Johann Sebastian Bach created two monumental canon cycles in his Art of the Fugue and Goldberg Variations. Arnold Schoenberg, Anton von Webern, and Paul Hindemith employed the technique extensively in the 20th century. Canons also occur in folk music - e.g., in the Balkans and in Africa.

Pachelbel's Canon was originally written for three violins, she explained, but it can easily be arranged for a string quartet or the organ, keyboard and synthesizers, all creating a different sound depending on the occasion.

Bach wrote a crab canon as part of his Musical Offering to King Frederick the Great in 1747. A crab canon is a single line of music that can be played with itself in retrograde (i.e, played backwards), as demonstrated in this video.

Shakespeare and Chaucer are part of the canon of Western literature, so you might read their work in an English class. A canon can also be a body of work, like the Shakespeare canon, which includes all of the Bard's plays and poems.

A canon is a piece of voices (or instrumental parts) that sing or play the same music starting at different times. A round is a type of canon, but in a round each voice, when it finishes, can start at the beginning again so that the piece can go “round and round”.

It was popularised in a film, Ordinary People, but this was not really connected with marriage. Instead, it seems to have been picked up from that film, and gradually become accepted in wedding ceremonies because of its extremely attractive sound.

Bach was a master of virtually every musical form of his day. He mastered the church organ and the scoring and presentation of German church chorales. We see this in the able and often brilliant chorale-based cantatas he churned out weekly over several years during his tenure in Leipzig.
