Step 2: Add hooks and verses
Nearly every rap song consists of three basic parts: intros, hooks (choruses) and verses. Occasionally, you'll see some other elements, but usually rappers stick to these three.
Most songs begin with some instrumental bars, which are typically followed by a verse, although some do start with a hook. Very few songs begin with rapping. Usually the beat plays for 4 or 8 bars before the rapper comes in.
After the intro, most songs contain two to four verses of 16 to 32 bars each. The verse is the largest section of a song and usually contains the bulk of the information. When instructing your students, have them sketch out the song by dividing the academic content into verses that make sense. Verses are often of equal length, such as 16 bars each. However, they can also have different lengths.
After the first verse comes the hook, which is the most memorable (and often most important) part of many hip-hop songs. There are basically two types of hooks: rapped or sung. Many hooks incorporate both of these techniques. All kinds of rappers write the rapped hooks, while pop-type rappers favor the sung hooks. As your students are writing their hooks, know that they have these options.
It's important to have the hook accomplish two things. First, it must be fun to listen to, because it's the part that listeners are going to hear the most. This, I'm sure, is what The Sugarhill Gang was thinking about with this hook on "Rapper's Delight":
I said a hip-hop, the hippie the hippie,
To the hip hip-hop, uh you don't stop the rockin',
To the bang bang, say up jumped the boogie,
To rhythm of the boogie the beat.
That hook doesn't make any sense, but it is fun and oddly catchy. The second thing most hooks should do is advance the main idea of the song. Often, the best hooks do this without being obvious. Take this example from Jay-Z on a track where he basically just brags:
Can't touch the untouchable, break the unbreakable
Shake the unshakeable (it's Hovi baby)
Can't see the unseeable, reach the unreachable,
Do the impossible (it's Hovi baby)
He doesn't use the hook to come out and just say, "I am awesome," but that is the message. Since your students are writing an academic song, they'll want to think of a hook that can complement the subject. Students should always come back to the hook once they've written the whole song to see if they can improve it. Hooks are extremely important.
