When we listen to some foreign rappers, even if we don't understand the lyrics, we will feel that they sound smooth and comfortable, because they flow well.
The soul of a rapper is probably flow. Every rapper's fighting on the battlefield, in addition to having huge and sharp words, the most important thing is to use their own unique flow to integrate them into their powerful weapons.
Extended data:
Rhythm: Rhythm is very important, especially knowing the beat, the rhythm and beat of accompaniment. Whether you have a musical theory foundation or not, it is relatively easy to grasp the rhythm of the beat. You don't necessarily need to understand 4/4 beats and how much BPM it is. You just need to grasp the basic drums and try to keep the rhythm of your rap in tune with the rhythm of the drums.
Rhyme: If you want your rap to sound good and catchy, you should use rhymes in your poems. Simple and easy to use is the rhyme at the end of the sentence. Of course, there are many forms of rhyme.
Chinese lyrics: It is difficult for people who have just started to improvise freely to produce lyrics. If you want to come out freestyle, you still need to practice more. When you are free, you can think for yourself or write lyrics for practice.
English lyrics: If you want to add English to say lyrics, you must first learn English well. Pronunciation and continuous reading are very important. Because there are many slurs, missing sounds, swallowing sounds and so on in rap. Secondly, we must master the rhythm and beat. Personally, I think this is the most critical.
