Eight beats are relatively simple in rhythm, and each beat corresponds to a word, which means that within the eight beats of the same accompaniment, a word corresponds to a drum.
In contrast, Sixteen beats are faster and more complicated. Under the same accompaniment, a drum beat corresponds to two words, that is to say, each beat corresponds to two words.
therefore, 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.
