Introduction:

Melody is the primary element of music, which usually refers to an organized and rhythmic sequence formed by artistic conception of several musical notes. According to a certain pitch, duration and volume, it has a single voice with logical factors. Melody is composed of many basic elements of music, such as mode, rhythm, beat, strength, timbre performance methods and so on.

melody consists of two elements, namely, melody line (or pitch line) and rhythm. In the process of continuous melody, various linear or curved processes are formed due to the direction of pitch, which are similar to the stretching or ups and downs of lines in the picture, so they are called melody lines.

With regard to the time of sound, melody can form all kinds of syntax and structure of music only when the sounds with different pitches (i.e. melody lines) are combined with the performance functions such as the length, speed and pause of various musical rhythms.
