Rhythm, intensity, speed, melody, mode, harmony, musical form, texture, and timbre.

1. Rhythm: The rhythm of music refers to the length and strength of the mid-tones in the music movement.

2. Intensity: the intensity of the volume in the music. Tempo: How fast or slow the beat of the music is.

3. Melody: Melody is also called tune. The ups and downs of the music are organized horizontally in an orderly manner according to a certain rhythm to form a melody.

4. Mode: The tones used in music are connected according to a certain relationship. These tones form a system centered on one tone (the main tone), which is called mode. Such as: major mode, minor mode, pentatonic mode, etc. The notes in the mode, starting from the tonic note and arranged from low to high, form a scale.

5. Harmony: Harmony includes "chords" and "harmonic progressions". The horizontal organization of chords is the harmonic progression.

6. Musical form: the arrangement of musical materials, that is, the structural layout of musical works.

7. Texture: the combination form of each voice part in a polyphonic musical work (including vertical and horizontal combination relationships).

8. Timbre: Timbre can be divided into human voice timbre and musical instrument timbre. The human voice can be divided into children's voice, female voice, male voice, etc. The differences in the timbres of musical instruments are even more varied. In music, sometimes only a single timbre is used, and sometimes a mixture of timbres is used.
