The title refers to the number of rappers with 16 or more bars. Rap is generally divided into “choreography” and “motivation.” In other words, a rapper gets a title for their lyrics and is given bars by producers for their production. A rapper has 16 bars for this reason: If they do a good job and write good lyrics, they can continue to be rappers until they reach the next level, whereas if the lyrics are bad or contain grammatical errors, they will get dropped down to “underclassmen” in the next tier below (or “underclassmen of the underclass,” in the case of an MC who is not considered a rising star).
So what bars are not in rap? Well, the following are not in rap:
Lyrics that don’t have a direct relation to the topic of the song
Vocals with long pauses (or a pause) in a rap
This rule refers to the rappers who don’t have a clear and distinct idea of how a rap verse is supposed to go. For example, on “Rapper’s Delight,” KRS-One never says, “This is what you should do,” so KRS-One isn’t a rapper. He’s a producer for a rap album whose music has no connection to the lyrics. Thus, he would have no bar count, but he is still a rapper. He hasn’t developed a rap flow for the chorus of the verses of the song. This is why Eminem’s verse on “Where Are Ü Now” is completely overblown, but it is still on the album because it is the most popular song on there.
The rule has been around for years and we are constantly changing our views because the new era of rap has brought us a generation more interested in rap and it has given us the ability to write something different from the original. We don’t see any reason to take it back and start over, though. What we need to do is find newer songs that are more in the spirit of rap and that can be an even bigger hit for us.
What are the limitations of the 16 bars rule?
You have to know at least 5 bars for each beat. This makes certain things a bit more difficult:
Dances are very limited as they don’t allow more than 6 bars when they are on the beat, so you can only count down to 6 beats after you complete one. It is possible
