Rhythm, melody, harmony, timbre.

Rhythm: The rhythm of music refers to the length and strength of the musical 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.

Melody: the primary element of music. Usually refers to an organized and rhythmic sequence of several musical sounds formed through artistic conception. It is performed as a single part with logical factors composed of a certain pitch, duration and volume. Melody is an organic combination of many basic elements of music, such as mode, rhythm, beat, dynamics, timbre performance methods, etc.

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.

Tone: It means that the frequency of different sounds always has distinctive characteristics in terms of waveforms. Different objects vibrate with different characteristics. Just like the leaves in the world are all different. Different sound emitters have different timbres due to their different materials and structures. For example, pianos and violins have different sounds than people; each person's sound will also be different.

Extended information

Music is an art that reflects human emotions in real life (English name: music; French name: musique; Italian: musica).

Music can be divided into two major types: vocal music and instrumental music, and can be roughly divided into classical music, folk music, original music, modern music (including pop music), etc. Among art types, music is abstract, and music can be divided into Eastern music and Western music from the historical development.

The ancient Chinese theory in the East, led by Chinese Han music, is based on the pentatonic scale, that is, Gong, Shang, Jiao, Zheng, and Yu, while the West is based on the heptatonic scale. Music is pleasing to the eyes and brings auditory enjoyment to everyone. Music can improve people's aesthetic ability, purify people's souls, and establish lofty ideals. We express our emotions through music and release many of our emotions.
