The lyrics to a song can be an important part of the story. They can evoke emotion, set the mood and bring fresh ideas to a writer's mind.
When writing songs, it's best to listen to other songs and study their lyrics to see how they work. This will help you create a strong melody that suits your lyrics and creates an effective musical structure.
Some artists start by thinking of a topic and build around that idea, while others will try to come up with a title first. Either way, you can use your original inspiration to make your lyrics personal and unique.
Music is a powerful way to express emotions, so you should always try to write lyrics that are meaningful and relevant to your audience. You can do this by using real-life events or experiences as your inspiration. The best way to get inspired to write a new song is by reading a book that's related to the music you're trying to create. For example, the story Making Records: The Scenes Behind the Music by Phil Ramone is a great read for those looking to learn how to write music.
Reading about other musicians can also be helpful, as it can provide you with a better understanding of how other artists approach the music industry. For example, when writing a rap song, it can be useful to listen to a few rap songs and compare the lyrics with what you're trying to accomplish in your own songwriting career.
