Question:

How do some people rap so well?

Did you guys memorize a rhyming dictionary or something and how did you guys start out? Is there anyway I could practice at home so I could start freestyling and stuff?

Best Answer - Chosen by Asker: People rap well by rehersing and by rythm and flow which you could memorize easily by the music tone and rap with it. Use what you think what you've learn and what ryhmes good.
have fun.
