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.
N=8, j=10: the eight-bar linkage has 16 different topologies; N=10, j=13: the 10-bar linkage has 230 different topologies, N=12, j=16: the 12-bar has 6856 topologies. See Sunkari and Schmidt for the number of 14- and 16-bar topologies, as well as the number of linkages that have two, three and four degrees-of-freedom.
