how many bars in rap
Figure out how many bars you have to rap on. A bar is simply one line of your song. Most raps are built out of 16 or 32 bar verses though they can be as short as 8 or 12 bars as well. If you're writing the whole song yourself you might have 2-3 verses and a hook. You might also have a short 8-10 bar bridge, which is a short verse with a slightly different beat or structure.
In rap, an industry verse is supposedly 16 bars; and a bar is typically a line, but sometimes rappers might rhyme like 2-3 words with the previous line? o.O How would 16 bars be defined in that case?
