Different forms of music can express different thoughts and feelings.

first, the form of music

Music form includes the following three aspects: basic elements, various organizational means, and the medium between basic elements and organizational means-the laws and regulations of formal beauty.

1. The basic elements of music are melody and rhythm, including rhythm, melody, harmony, dynamics, speed, mode, form and timbre.

2. The operating basis of organizational means on various basic elements is the law of formal beauty of music, such as symmetrical balance, tonal contrast, rhythm and rhythm, natural harmony, diversity and unity, which is the crystallization of people's generalization of various forms of beauty in real life and nature in long-term aesthetic activities.

3. Music form embodied in space is a spatial illusion that people rely on hearing to judge. This illusion is reflected and exists in space through the level of sound, the change of timbre and different combinations, which makes people feel the richness of sound itself in auditory space.

Second, the content of music

The content of music needs to be reflected in some way, and its clarity or vagueness mainly depends on the different types of music thinking, that is, the characteristics of different music genres in music conception. There are two ways to express it:

1. Non-musical content

The content expressed or explained by literary language or some visual image is abstract and needs to be realized by subjective imagination, so we call it non-musical content.

2. Musical content

Another way of expression is that the audience can feel the content factors reflected by the logic of the sound itself in an intuitive way without using words or images. This way of expression is direct and concrete content, which we call musical content.
