Why do most songs have to repeat the lyrics twice?

Usually, it is the core part of the whole song, that is, the climax part, which will be sung twice in order to make it easier for the audience to remember the song. There are many songs whose lyrics are not repeated twice, but repeated until the lyrics get louder and louder until there is no sound.

Personal opinion, for the audience, there are three reasons for singing twice:

First, let others remember the lyrics; (Simple, easy for others to listen and learn)

Second, I can find my own feelings; (I'm sure I can tune it once and twice.)

Third, if the four-minute song is different from the lyrics, it will be very difficult. (You need to remember the lyrics)

For the creator. Repetition is the main means to express the key points of music! Make it easier for listeners to understand and remember. Pop music is easy to remember and sing, so as to achieve the purpose of wide spread, and repetition is an indispensable method.

This has formed a strict musical structure system, which is simplified from the development of classical music. This music progress system has been formed for hundreds of years, and the main >: genus > main > subordinate > genus > main TSD cycle. This kind of standard music is generally accepted by people. If anyone doesn't use this routine in pop songs, it is: 1. Well done, unconventional, and nice; 2. The public cannot accept it.

If you carefully divide the phrases when listening to the song (from the analysis of the music itself), the structure will come out. Analyze a few more songs and find that everyone is the same.

Therefore, at present, the chorus of most songs in China is generally sung twice, which is due to market reasons and a large part of historical and cultural reasons.

I hope my answer can help you.
