What is the expression form of music? Be professional.

Music can be divided into vocal music and instrumental music.

Vocal music refers to the musical form of singing with human voice. Vocal music is a pleasant, continuous and rhythmic sound based on human vocal cords and acting on breathing through mouth, tongue and nasal cavity. According to the range and timbre, it can be divided into soprano, mezzo-soprano, contralto and tenor, baritone and bass. The range of each human voice is about two octaves.

Compared with vocal music, instrumental music is completely played by musical instruments without human voice or human voice in a subordinate position. Musical instruments can include various stringed instruments, woodwind instruments, brass instruments and percussion instruments. Some instrumental music also uses some parts as effects, but some composers sometimes add some parts, such as the chorus of Ode to Joy in Beethoven's Ninth Symphony, but generally speaking, symphonies belong to instrumental music rather than vocal music.

Music refers to the art of melody, rhythm or harmony composed of human voices or musical instruments.

Music is an artistic form that expresses people's thoughts and feelings and social real life with auditory images composed of organized voices. It is also one of the most touching art forms. When the melody rings, people tend to be irresistibly immersed in the musical atmosphere immediately. Any art form has its own way of expressing ideas and shaping artistic images. For example, dancing is through body movements and facial expressions, painting is through lines, colors and composition, and literature is through words, phrases, sentences and articles to reflect artistic images. Usually, people distinguish different kinds of art through different expressions, such as different musical instruments. Music can also express the intention of musicians and music creators.

In the Book of Rites, it is recorded in detail that "all sounds are born by people's hearts, moved by people's hearts, made by things, and moved by things, so they are shaped by sounds and corresponding to sounds, so they change." This introduction simply and clearly covers the relationship between the sound change of music and people's feelings. If we consult the ancient books and further scrutinize them, we can have a deeper understanding of the meanings of the music words we usually hear.
