The concept of canon appears in the field of music.
The musical canon
In music , canon is understood as the polyphonic composition in which the voices are introduced successively, each one imitating the song that precedes it. The original voice is called a proposal; a certain number of measures away, the voices that are known as the response begin.
At the end of the 17th century, the German composer Johan Christoph Pachelbel wrote one of his most remembered works: the Canon in D major for three violins and basso continuo. This piece enjoys great popularity in both the academic and popular environments, and undoubtedly contributed considerably to the acceptance of the canon as a type of composition .
Other great composers, such as Haydn and Mozart, have written canons in their works, although Bach took this form to its splendor, which was lost with the arrival of romanticism , where the text and the message became more important than the melodies.
Classification according to type
Depending on the transformations that the voices undergo, several types of canon are distinguished, among which are:
* Circular canon : also called infinite, it is one where the repetition could never end, given its structure;
* Spiral canon : in each response, a modulation occurs with respect to the previous voice, making its execution very difficult, especially if it is a sung piece;
* Contrary motion canon : repetition is the inversion of each interval of the canonical theme, where in general the type of interval is maintained diatonically, which does not guarantee that the resulting tonal distance is the same. A clear example is taking the line DO RE and generating the canon DO SI, where the major second becomes a minor second , since between DO and RE there are two semitones and between DO and SI, only one.
