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.
