Freestyle in a language other than English. This can be your mother tongue, or a language you have been learning.
Sometimes you hand someone the mic they say, “I’m sorry, I don’t know English very well.” Who said we have to freestyle in English? If you know another language, either your first language or a language you are just learning, use that language while freestyling! If it’s a new language for you, it might be hard at first, either because you don’t know that language very well, or because you haven’t freestyled very much using it. As you practice and get better, you might find it greatly increases your abilities in that language. Often people exhibit a totally different style when they change languages. Some languages are great for freestyle because almost every word rhymes with the next. When you’re proficient in several languages try alternating between them while you are freestyling for maximum effect.
