In rap music, eight beats and sixteen beats are common rhythm division methods, and their main difference lies in the complexity of speed and rhythm.

The rhythm of the eight beats is relatively simple, and each beat corresponds to a word, that is, within the eight beats of the same accompaniment, a word corresponds to a drum.

In contrast, sixteen beats is faster and more complicated. Under the same accompaniment, one drum corresponds to two words, that is, each drum corresponds to two words.

So the main difference between eight beats and sixteen beats lies in the complexity of speed and rhythm. In addition, different singers or songs may have different singing methods, so in practice, these common rhythm division methods may also change.
