To get lyrics on stories, you could try looking up the song on popular music streaming services like Spotify or Apple Music. They often display the lyrics along with the song. You can then copy those lyrics and add them to your story.
You can incorporate lyrics by having characters sing or quote them within the story. Maybe have a musical scene or a moment of inspiration where the lyrics fit the mood.
To write lyrics in a novel, start by considering the character who'll be singing or the context. Make the lyrics fit the story's style and genre. Also, pay attention to rhythm and rhyme to make them more musical and engaging.
You can weave the lyrics into the narrative by having a character sing or hum them at a relevant moment. Or, use the lyrics as inspiration for the mood or theme of the story.
You could use them as a theme or motif throughout the story. Maybe have a character constantly reflecting on the meaning of the lyrics or have events that mirror the emotions expressed in them.
One way to add lyrics is to have a character sing or hum them. Another approach is to use them as a form of internal monologue to express emotions. Also, you could mention the lyrics in the narrative description to set a mood.
