Is there any difference between chord and melody except pronunciation?

Melody: Melody, also called tune, is the basic element of music. The organized and rhythmic harmonious movement formed by several musical notes through artistic conception. It is a single voice with logical factors, which is based on a certain mode and beat, according to a certain pitch, duration and volume.

Chord law: refers to the organized progress of several notes in a specific musical thought, which is standardized and shaped by the changing time rhythm and the lines of rising and falling notes. There is no word "string law" in Ci Hai. "String" has only one sound "String". -"Chord law" is not "melody"

Legal terms:

Chord law: Because of the difference between chord vibration and air column vibration and their calculation methods, it is one of the calculation methods of China ancient method. Chord law is called chord law, which is the symmetry of pipe law. It is characterized by the calculation rule of chord length according to chord length standard.

The advantage of chord law is that the data is accurate, and there is no need to calculate the "nozzle correction" like the pipe law. However, due to the uncertainty of string tension, the tools used in string law are unable to determine the pitch of the yellow bell; The pitch of the external standard (just like the modern international pitch is based on c 1 or a 1) still needs to be determined according to the pitch of the "yellow bell". Given this sound, other pitches are determined by string law data; The simplicity of the method and the accuracy of the pitch are unparalleled. The traditional tool of chord law (positive regulator) is called chord accuracy. In Guoyu, pigeons in Lingzhou call it "average clock", and Han and Chen Zhongru in the Northern Wei Dynasty call it "quasi". Wang Pu and Zhu Zai in the Five Dynasties called it "Fa". In the history of China, all kinds of stringed instruments are multi-stringed instruments shaped like Qin; It is different from the European string gauge.

Traditionally, the data of chord law is based on "inch", which seems to be the size of the law tube on the surface, but in fact it is to change the inch into a ruler.
