Different rhyming schemes are available to rappers, from AABB to AXXA. These rhyming styles dictate which words rhyme in your lyrics. Study them and develop your rhyming versatility.  Most verses in rap songs are "16 bars" or 4 sets of 4 lines of lyrics in a song. Start with simple rhyming schemes like ABAB and build up to include more complex rhymes. An example of an ABAB rhyme is "That cat, over there, in the hat, on the bear." The last word in the first and third lines rhyme as well as the last word in the second and fourth line. Some rhymes are known as half-rhymes if they have similar sounding ending consonant sounds but do not fully rhyme. An example would be "bald" and "held." Some artists get so complex and into their art that they forget that it must also appeal to the general audience. As you build up your lyrical skills, make sure to keep the listener in mind and don't get too fancy or else you may lose fans.  Taking risks are a part of being a popular artist, but sometimes you can lose fans if they don't like the direction you're going in. Just because a song is catchy does not mean that it has to lack substance. The hook is the part of the song that is often repeated and is the portion of the track that's usually most remembered by fans. For other genres of music, this is typically referred to as the chorus. Having a good hook in a song is incredibly important if you want it to be popular. The hook should be catchy, memorable, and should embody the song.  A popular hook from the past is Chamillionaire's "Ridin Dirty." "They see me rollin', they hatin', Patrollin' and tryna catch me ridin' dirty. Tryna catch me ridin' dirty."  If you aren't a singer or aren't good with hooks, consider collaborating with an R&B singer who would be better equipped. Think of something that helps support the verses in your songs. Regardless of how popular or famous you get, it's important to stay on the top of your game. Rapping is a skill that requires discipline and practice so make sure to regularly practice to work out your rapping abilities.  Take every opportunity to show other people your songs and get feedback. Practice in front of the mirror, while you're in the car, or taking a walk.
Master the various rhyming schemes that exist. Build up your rhyming ability but keep it catchy. Have the ability to deliver a good hook. Never stop practicing to stay sharp on your wordplay.
