An art that uses organized music to express people's thoughts and emotions and reflect real life. Its most basic elements are rhythm and melody.

Basic elements of music: The basic elements of music refer to the various elements that make up music, including the pitch of the sound, the length of the sound, the strength and timbre of the sound. These basic elements are combined with each other to form the commonly used "formal elements" of music, such as rhythm, melody, harmony, intensity, speed, mode, musical form, texture, etc. The formal elements that constitute music are the means of expression of music.

The order from low to high can be divided into:

1. Rhythm: The rhythm of music refers to the length and strength of the mid-tones in the music movement. The rhythm of music is often compared to the skeleton of music. Beat is the periodic and regular repetition of heavy beats and weak beats in music. Traditional Chinese music calls the beat "banyan", "ban" is equivalent to the strong beat; "eye" is equivalent to the sub-strong beat (middle eye) or weak beat.

2. Strength: the strength of the midrange of the music.

3. Speed: how fast the music progresses.

4. Melody: an organized, rhythmic and harmonious movement of sound formed through artistic conception. Melody is the basis of music, and the thoughts and feelings of music are expressed through it.

5. Harmony: Harmony includes "chords" and "harmonic progressions". Chords are usually sound combinations formed by three or more tones that overlap vertically (simultaneously) according to certain rules. The horizontal organization of chords is the harmonic progression. Harmony has obvious color effects of thick, light, thick and thin; it also has the function of forming phrases, dividing sections and ending music. Progress upward with a 3-degree relationship.

6. Tonality: the harmony produced on a scale. There are 24 major keys in the music industry (major key = key)

7. Musical form: the horizontal organizational structure of music.
