1. Feel the rhythm and melody of the song, and let your body and mind blend into the atmosphere of the song.
2. To sing the memory of lovelorn love and the pain that can't be given up, we need to use voice to convey this emotion. Try to use a soft and emotional voice in the chorus and bridge part of the song, and use a stronger voice and emotion in the climax part of the song.
3. Pay attention to the lyrics in songs, especially those sentences that express nostalgia and helplessness for past love. When singing, try to convey the feelings expressed by these lyrics with your voice and emotions.
4. Adding some pauses and breathing in proper places can help you control your voice better and convey the emotion of the song.
If you still have questions about how to use voice and emotion, you can seek the help of a professional vocal coach or recording engineer, who can give you more specific advice and guidance.
The most important thing is that singing should be based on the love of music and the emotion of songs, rather than reaching a certain level or winning the recognition of others. I hope that through this song, you can express your nostalgia for the lost love and the pain you can't give up with your voice and emotion.
