A short note
Broadly speaking, rapping is an artistic form of vocal delivery that incorporates rhyme and rhythmic speech. It is often performed over a backing beat or musical accompaniment. A rap song has a content (lyrics), flow (rhythm/beat and rhyme), and rendering (spoken word art, sing-song speech with cadence and tone). When used for academic content delivery, 16-bars is the amount of time that a student or a teacher is generally given to perform a verse. Here one bar is equal to four beats of music. However, adaptations and improvisations are allowed by the teacher or students attempting non-rap use rap for cognitive and non-cognitive gains. Even attempting rap-like verses is great mental effort for mindful engagement with the subject matter
