How do songwriters distinguish between writing lyrics and composing music?

The author of a song can be divided into two types: lyricist and composer. The lyricist is the author who is responsible for completing the content of the song, and the composer is the author who is responsible for arranging, conducting, arranging and playing the musical elements. Usually, the lyrics and songwriters of songs can be different.

In the process of song creation, the lyricist is responsible for completing the lyrics creation of the song, creating lyrics according to the requirements of the theme, emotion and style of the song, and expressing the connotation and emotion of the song through the lyrics. The composer, on the other hand, based on the lyrics and according to the music requirements of the song, creates a score including melody, harmony, rhythm, music style and other elements, and finally completes a complete song work.

In the actual creation process, the cooperation of songwriters is closely related, and they will communicate and cooperate with each other to jointly complete the creation of a song. The songwriter of the final song is based on the overall creativity and music quality of the work, not named after himself.
