This is the Bass part for a German hip-hop song. The whole song features the same bass line as follows G|------------------|-------------------| D|---------7---9----|-------------------| A|---------------7--|---5-6-7-----------| E|-7----------------|---------4---5--6--| B|------------------|-------------------| You can, of course, use a four string bass since the bottom string is not required, but remember to be funky.
