It’s the combination of two elements and it determines the rapper’s overall sound. Those two elements? Intonation techniques, and rap rhyme scheme. If you want to understand a rapper’s flow, pay attention to those two elements.
The essence of a hip hop rhyme scheme is choosing what rhyme words you’ll use, how many you will have and where you will put them. You may find a rap rhyme dictionary helpful to this process.
While the intonation is simply the rise and the fall of the voice. The fluctuations, if you will. Consider the sentence “I never kissed your wife,” and by placing the intonation on a different word each time that same sentence can have five different meanings. Intonation stems from emotion, and feeling.
It’s vitally important to a great rap flow and every rapper will do it different. Think of it as the spirit of your rap rhyme scheme. Without intonation, there is no life, no passion- it’s boring. Throw in the intonation pattern and you breathe life into it.
There are several combinations of rap flows, there is no limit. Imagine two rappers write an identical rhyme scheme… if they both apply different intonations the same scheme will sound completely different.
