Clear enunciation is important in rapping techniques. Especially since rappers hold the microphone close to their mouth while performing. Over enunciating your words into the microphone will allow the listener to hear the rapped words clearly. Simple exercises like saying tongue twisters on a daily basis will help train your tongue to relax and enunciate well without stumbling over words. Learning to speak slowly and over enunciate will also help develop good rapping skills.
Beginning rappers may find themselves running out of breath before they are finished with their lines. Raps may sound forced, strained or weak into the microphone if you run out of breath before you are done with your rhyme. Listeners will not be able to understand or hear your lyrics this way. Learning to breathe in between rapping lines is important for mic sound quality. Being conscious of your breathing while rapping into a mic will help keep you focused and not run out of breath.
Beat boxing is a way of creating your own hip hop style of beat using your mouth and lips to make the sound alone. The way you hold the mic while beat boxing is crucial to sound quality. The mic is held very close to the mouth and is usually cupped with the other hand to help produce the unique sound of beat boxing. You also can hold the mic with one hand covering most of the mic. It creates a funnel for the sound to enter the mic.
Practicing the breath control and enunciation while performing raps will help perfect your skills. Practice breathing in between your rhymes, enunciate well and learn to incorporate beat boxing into the mic. Learning these skills will help fine tune and find your rapping style, creating good sound quality into the microphone.
