"Rhyme styles

See also: Rhyme scheme

Aside from "flow" (the voice and tone of a particular MC), and rhythmic delivery, another central element of rapping is rhyme. In classical poetry, rhymes that span many syllables are often considered whimsical, but in hip hop the ability to construct raps with large sets of rhyming syllables is valued. Rap can contain any and all forms of rhyme found in classical poetry such as consonance, assonance, half rhyme, or internal rhyme.

In the early years of hip-hop, now known as "old-school hip-hop" rap was characterized by simple rhyme schemes and standard refrains. The 1979 song "Rapper's Delight" by The Sugarhill Gang, the first recorded rap song, was typical of the style, with Big Bank Hank rapping:

Just throw your hands up in the air,
and party hearty like you just don't care.
Let's do it, don't stop, y'all,
a tick-a-tock, y'all, you don't stop.

The rapper Rakim, still often regarded as one of the greatest MCs ever, is widely credited with introducing internal rhymes and a more mature sensibility to rapping. The 1986 debut single of Eric B. & Rakim, "Eric B. is President", begins:

I came in the door, I said it before
I never let the mic magnetize me no more
But it's biting me, fighting me, inviting me to rhyme;
I can't hold it back, I'm looking for the line.

By the 1990s, many rappers had adopted more sophisticated rhyme styles. A well-known example of the use of internal rhyme from that time period is found in Big Pun's 1998 song "Twinz", in which he raps:

Dead in the middle of Little Italy, little did we
know that we riddled two middlemen who didn't do diddly.

Modern rappers have different styles of rhyming. Juelz Santana often avoids full rhymes in favor of assonance, consonance, half rhymes, and internal rhymes. Eminem, on the other hand, often focuses on complex and lengthy multisyllabic rhyme schemes, while "flowas" like Rakim use metaphorical, emotional rhyming, and story telling to communicate a message.

Literary technique

Main article: Literary technique

Rappers use double entendres, alliteration, and other forms of wordplay that are also found in classical poetry. Similes and metaphors are used extensively in rap lyrics; rappers such as Fabolous and Lloyd Banks have written entire songs in which every line contains similes, whereas MCs like Rakim, GZA, and Jay-Z are known for the metaphorical content of their raps. Lil Wayne is also known for his frequent use of smilies and metaphors.

Hip hop lyrics often make passing references to popular culture and other topics. An example is the song "Wu-Tang Clan Ain't Nuthin' Ta Fuck Wit" by the Wu-Tang Clan, in which RZA rhymes,

I be tossin', enforcin', my style is awesome
I'm causin more Family Feuds than Richard Dawson
And the survey said - you're dead
Fatal flying guillotine chops off your fuckin' head

Such allusions serve to illustrate or exaggerate a statement, or are simply used for humor. Some of these references are overtly political, while others simply acknowledge, credit, or show dismay about aspects of the rapper's culture and life.

Diction and dialect

Many hip hop listeners believe that a rapper's lyrics are enhanced by a complex vocabulary. Kool Moe Dee claims that he appealed to older audiences by using a complex vocabulary in his raps.[16] Rap is famous, however, for having its own vocabulary—from international hip hop slang to regional slang. Some artists, like the Wu-Tang Clan, develop an entire lexicon among their clique. African American Vernacular English has always had a significant effect on hip hop slang and vice versa. Certain regions have introduced their unique regional slang to hip hop culture, such as the Bay Area (Mac Dre, E-40), Houston (Chamillionaire, Paul Wall), Atlanta (Ludacris, Lil Jon, T.I.), and Kentucky (Nappy Roots). The Nation of Gods and Earths, a religious/spiritual group spun off from the Nation of Islam, has influenced mainstream hip hop slang with the introduction of phrases such as "word is bond" that have since lost much of their original spiritual meaning.

Preference toward one or the other has much to do with the individual; GZA, for example, prides himself on being very visual and metaphorical but also succinct, whereas underground rapper MF DOOM is known for heaping similes upon similes. In still another variation, 2Pac was known for saying exactly what he meant, literally and clearly."
