Composition is a separate melody line, which refers to the main melody "tune" we hum. Composing music is also composing. Arranging is arranging the melody of the instrument and the method of playing the instrument.

Specific explanation

Composing is to complete the creation of musical content. A simple melody cannot determine the content that music wants to express. The overall sound effect of music including melody (if there is an obvious melody) and percussion (if there is percussion):

Including the selection and change of tonality, vertical pitch arrangement, and horizontal harmony Connection, part counterpoint, rhythm interleaving, timbre selection and matching, beat (and its changes) and speed (and its changes) are the keys to expressing music content, emotion, and atmosphere. Changing one of these factors may change the The content of the entire music. Identifying these talents is called composition.

Arranging is to expand the expression of the music without affecting the main melody and content of the original song. In modern music, especially pop music, composition and arrangement are often two people, because many composers only have the grasp and inspiration of the melody, while the arranger has more skills in how to embody the melody. To put it simply, the composer gives the skeleton, while the arranger gives the flesh and blood.

In classical music, there was originally no concept of arrangement, because all composers wrote their own scores and stipulated the coordination of all instruments. But with the passage of time, more expression methods were discovered in performances and daily practice, and at this time, arrangement appeared.

The English word for composition is composition/composition, which is the composition/composition of "organization". It is the integration, assembly, creative arrangement and use of materials. In early music, the work must be performed smoothly to complete the entire composition work.

Furthermore, creating music that can be performed is considered composition. With the development of music production technology, even if some parts are not performed in the end, or some speakers are not suitable for real performance or cannot be performed, the desired musical effect can be obtained through electronic equipment. So today it seems that composing some music even without the final steps of performance is considered composition.

Composing is completing the creation of musical content. All elements in music serve the musical content, and every voice is equal. Any music form (including monophonic music and pure percussion music) will at least include texture, form, arrangement, speed, and beat. Changing one of these factors may change the content of a piece of music, and identifying these talents is called composition.
