Canon, a polyphonic music, originally means "regularity". The tune of one voice chases another voice from beginning to end, until the last ... the last summary, the last chord, they will blend together and never separate. Extremely touching music, just like two people living together. Canon Canon is the name of a musical form, which is characterized by repeating the same piece of music at intervals of several syllables. The general playing method is to start with the cello and add three violins every eight beats. All violins play exactly the same melody, with only three different melodies before and after, and each one has only two bars for repeated playing; The melody of the cello is only two bars from beginning to end, repeated as many as 28 times, but the listener is intoxicated with this melody and will not feel monotonous at all. Simple is simple, complex is complex, and the author can say that he has reached the realm. The writer is johann pachelbel (1653 ~ 1706), a German, who used to be Bach's teacher. However, some people say that it was an unknown composer at that time. In order to sell this song, he passed off the works of the famous Pacabel at that time. A polyphonic music form composed entirely of imitation. When every voice that has entered successively plays (sings) a melody at the same or different pitch from beginning to end, it is called cannon. The first part of it is called the opening sentence or the main sentence, and the latter part is called the response sentence or the answer sentence. There are many kinds of guns, mainly including: ① Regular guns. The main sentence and the answer sentence are exactly the same in direction and rhythm, and are generally called according to the distance between them, just like Ducanon, Ducanon and Ukanon. In the regular canon, except for the same degree and octave, the canon of other intervals often imitates freely to avoid tonality overlap; Among them, the 45-degree gun can not only keep the tonality unified by free imitation, but also make the answer become subordinate or subordinate by strict imitation. (2) Variable grid gun. Answer sentence is the deformation of the main sentence. If the duration of the main sentence doubles, it becomes an increasing gun, on the contrary, it becomes a decreasing gun; If the sound of the main sentence is imitated in reverse, it is called reflection gun or anti-gun; If you imitate the sound of the main sentence in reverse order, it is called a retrograde gun or a crab gun; If you answer the sentence backwards and reflect the main sentence backwards, it is called a retrograde reflex gun. In addition, there are other forms of guns, such as double guns or three guns, that is, there are two or three pairs of guns with different melodies at the same time; There is no end to the cannon, that is, the end of the cannon is connected with the beginning of music, which makes the music cycle endlessly; There is also the last shot, that is, no longer imitating the answer, plus the ending part, to form the terminator. The earliest history of cannon can be traced back to folk music forms in13rd century, such as hunting songs and spinning songs. Rondo is a kind of small-scale acoustic music, which appears in the form of endless guns with the same degree that all parts enter at the same distance. /kloc-It was popular in Britain after the 3rd century. /kloc-a complete canon appeared in the 0/5th century, which was loved by Flemish composers. Since then, cannon is often used as an independent paragraph in small music or large music.

What is a cannon?

-

Canon is not a musical title, but a musical form, which literally means "singing in turn" and originally meant "regularity". Refers to a writing technique of polyphonic music. The melody of one voice follows another from beginning to end, and the same melody of several voices appears in turn, crosses, imitates each other, chases each other and entangles each other, while the voices are almost monotonous repetition. Until the last ... the last summary, the last chord, they will blend together and never part. Extremely touching music, just like two people living together. Music created by Cannon technique is called "Cannon music". Canon Canon is not as dramatic and thrilling as Romantic works, but it has produced various timbre effects in a seemingly repetitive and ordinary process. The ordinary rhythm is pulsating with ever-changing vitality, which makes people intoxicated and quiet like angels. The familiar Rondo is one of the cannon songs. Cannons appeared in the thirteenth and fourteenth centuries. Later generations often use ancient songs as the theme of guns. Such as Bach's "Five Variations of Cannon". /kloc-The symphony and sonata of the 0/9th century also used the Cannon technique, such as Beethoven's Symphony of Destiny.

Simply put, Canon is a composition technique, which means "playing the same melody in the order of two beats or one bar and two bars".

According to the principle of strict imitation, Cannon imitates the form of the original melody with one or more parts separated by a certain beat. As for what instrument to use and how many parts to use, it is up to the composer to decide. Generally speaking, 2-6 copies will be enough. It is not unreasonable for someone to write dozens of voices, which is common in modern music. Canon is one of the most basic polyphonic music. Generally, many composers have to do a lot of canon to practice their skills when learning polyphonic music, but they are just practicing. It seems that there are not many numbered works, but all kinds of musical instruments are available. There are many tutorials in Hindemith, such as flute and piano, viola and piano ... You can hear Canon in many places, not only Pachelbel's songs, but also Bach's. A large number of symphony works will use Cannon's skills, but they are not mentioned as a work alone like Bahabel. By the way, cannon doesn't have to imitate the melody completely. He can speed up and slow down the rhythm (which should be seen in Pahai Baird Mi Long), and he can also do reflex processing.

Other cannons

Besides the great Pachbel cannon, there are all kinds of cannons, among which there are many famous artists. For example, Bach wrote a variation on the clavichord called goldberg variations, which contains an aria and 30 variations, including the third, sixth and ninth, 12, 15,18,220. The first part of "Dance of Laurent Dole", the second suite of "City Girl" written by Bicai, constitutes a two-part octave cannon. Melody is first played by oboe, clarinet and violin. After two beats, bassoon, horn, viola and cello move the melody down eight degrees to imitate it. In modern opera, duets and choruses often take the form of cannons. For example, the quartet in the first act of Beethoven's opera Fei Tiglio is a four-part canon. In the second scene of the second act of Tchaikovsky's opera yevgeny onegin, a pair of friends Lenski and onegin became enemies. Before the duel, they also sang a gun. In the common sense of classical music, cannon is a polyphonic form similar to fugue.
