The hook is the chorus of your song. Some beginning songwriters find it easier to write the hook first, then compose the rest of the lyrics. Familiarize yourself with the beat and melody of the song, then try to write the chorus to fit that beat and melody.  Think of the hook as the thesis to your love song and try to sum up how you feel about your crush in a single statement. Brainstorm some ideas, then try to write the chorus based off those. You may write down a few keywords that come to mind when you think about your crush, such as “smart”, “strong”, “hot”, “brave”, or “sensual.” The lyrics for the chorus can be very simple like “Hit me baby one more time” or “Come on ride the train. Ride it!” You may combine a few keywords to create the chorus, “She’s smart, strong, and hot”, or “He’s brave, sensual, and strong.” Typically, the title of the song should also appear in the chorus. For example, if you use the chorus, “She’s smart, strong, and hot”, the song may be called “Smart, Strong, and Hot.” Part of what makes a good chorus is setting up and paying off a rhyme. There are many ways to set up the rhyming structure of your chorus and there’s no right or wrong way to go about doing it. Your options for the rhyming structure are:  Repeat the same line at least three times. If you choose to do this, make sure the line is fun to say or sing. For example, you may repeat the line, “I think you’re great” three times. When writing a four line chorus, rhyme the first line to the third line and the second line to the fourth line. For example, you may have the lines: “I think you’re great/We would be so good together/You’re the perfect mate/I think we could be forever.” Make the first and third lines the same and make the second and fourth lines the same. For example, you may have the lines: “I think you’re great/We would be so good together/You’re the perfect mate/I think we could be something special.” Make the first three lines the same, then diverge from the pattern for the fourth line. For example, you may have the lines: “I think you’re great/The perfect mate/I can’t wait/For us to be together.” Make all four lines completely different. For example, you may have the lines: “I think you’re great/We would be so good together/You’re my ideal/I want to date you.” There are many different places a chorus can go within the confines of a song. Most people choose to alternate verses and choruses, but there is no hard and fast rule on this.  Some songs repeat the chorus of the song over and over to help signify that the song is ending. If you choose to add a bridge, you’ll want to position an additional chorus after the bridge. Your chorus will continue to reappear throughout the course of the song, so it’s important that the chorus be catchy enough that your crush will want to listen to it over and over again.  Infuse the chorus with emotion to help show your crush how you really feel. You may talk about your feelings and emotions as well as the qualities that you appreciate in your crush. Another option is to write a chorus that sounds completely different from the rest of the verses. Try mixing up the rhythm or chord projections, changing keys or applying shifts in volume. If you know how, you can also add harmonies or instruments to enhance the chorus.

Summary:
Start with a hook. Determine the rhyming structure. Put the choruses in order. Make the chorus memorable.
