Methodology of improvised freestyle
Many rappers learn to rap through improvised freestyling, and by making freestyling into a conversation or a rhyming game which they play frequently as a way to practice, as described in the 2009 book How to Rap. Reasons for freestyling include entertainment, as a therapeutic activity, to discover different ways of rapping, promoting oneself, increasing versatility, or as a spiritual activity. Improvised freestyling can also be used in live performances, to do things such as giving something extra to the crowd and to cover up mistakes. To prove that a freestyle is being made up on the spot (as opposed to something pre-written or memorized), rappers will often refer to places and objects in their immediate setting, or will take suggestions on what to rhyme about.
