How do you write French song?

To write a French song, start by choosing a theme or emotion you want to convey, such as love, nostalgia, or joy. Next, brainstorm lyrics that reflect this theme, paying attention to rhyme and rhythm, as French songs often have melodic flows. Incorporate vivid imagery and expressive language to evoke feelings, and consider using common song structures like verses and choruses. Finally, add a catchy melody that complements the lyrics and enhances the overall mood of the song.
