Know and write for your audience. Rock music has the heaviest appeal among young people aged 12 to 25, so you must create lyrics topical to this age group. The best rock music is subversive and countercultural.
Decide on a subject. Popular subjects for rock music include romantic love, sex and break ups. You can be serious, but many successful lyricists write with their tongue firmly planted in their cheeks.
Write a rough draft for the first verse. The verses can rhyme, but don't have to. It's up to the composer to make nonrhyming lyrics sound catchy.
Create the chorus which connects the verses. It must be short and repetitive. Your chorus should relate closely to the title of the rock song.
Expand on the subject in your second verse. Explain the problem and relate an action. You must be concise. Your listeners want to dance, not listen to an opera.
Add to the story in the third verse. If your story has a twist, reveal it here.
Finish the rock song in the fourth verse. As in a good book, the fourth verse finishes the story and brings closure to the song.
