Giới thiệu Canon

Canon in D Hôm nay, tự nhiên muốn tặng TA, Ch và các bạn thích Canon (music) vài thông tin còn đọng lại từ Wiki. Ừa! không dịch, không phải vì chảnh, mà vì tôn trọng bản quyền (và he! he! hiểu chết liền...thiện tai! thiện tai) From Wikipedia: In music, a canon is a contrapuntal composition that employs a melody with one or more imitations of the melody played after a given duration (e.g. quarter rest, one measure, etc.). The initial melody is called the leader, while the imitative melody is called the follower which is played in a different voice. The follower must be created from the leader by being either an exact replication of the rhythms and intervals of the leader, or a transformation such as those listed in "types of canons" (below). Canons where all parts sing identical music and which repeat are called rounds, such as "Row, Row, Row Your Boat". A simple canon (also known as a round) imitates the leader perfectly at the octave or unison. Well-known canons of this type include the famous children's song Row, Row, Row Your Boat and Frère Jacques. The most popular canons heard today are from the Baroque period, such as Johann Pachelbel's Canon in D (Pachelbel's Canon), in which a canon between the three upper voices are accompanied by a repeating bass melody or ground, or every third variation in Bach's Goldberg Variations. Jean Sibelius's Sixth Symphony contains many hidden canons: for instance, a 3-in-1 in the strings in which each part is thickened to a third; a 4-in-2; a canon by diminution; and a canon with augmentations at two different speeds. What may be George Rochberg's best known work, his String Quartet No. 6, includes a set of variations on the Pachelbel Canon in D. Henryk Górecki's Third Symphony begins with an extensive eight voice canon in the strings. Steve Reich uses a process he calls phasing which is a canon with variable distance between the voices. History: The Old French canon, which meant 'learned', was taken from the Greek kanon for a rule or law, which eventually came to mean 'an accepted rule' in English, and the term was first used for the rule that describes how the voices relate to each others. Not until the sixteenth century was canon used to describe the musical form. The earliest known canons are the rounds (or rondellus) in England from the thirteenth century; the best known is Sumer Is Icumen In. In the fourteenth century many canons were written in Italy under the name caccia, and occasionally French chansons of that period used canon technique. During the period of the Franco-Flemish School (1430-1550), canon as a contrapuntal art form received its greatest development, while the Roman School gave it its most complete application. In the later periods the canon played a less important role (as entertainment), with a few notable exceptions like Bach's The Musical Offering. Arnold Schoenberg revived the interest in canon with his twelve-tone technique. Today Johann Pachelbel ( German composer Baroque baptized September 1, 1653 – March 3, 1706) is best known for his Canon in D; it is the only canon he wrote, and is somewhat unrepresentative of the rest of his oeuvre. In addition to the canon, his most well-known works include the Chaconne in F minor, the Toccata in C minor for organ, and the Hexachordum Apollinis, a set of keyboard variations.
