This is exercise I've learned from bass lessons video with John 
Patitucci.
I think it's very good for practising speed of fingers and also 
for some warming up.

It's movable so you can start from every fret... I tabbed it to 
show in what way was it played by Patitucci.

Part I ;)

G|————9—————10—————7——————8—————————————
D|—7—————8——————9—————10————————————————
A|——————————————————————————————————————
E|——————————————————————————————————————

Start slowly and then do it faster and faster. Stop when you want :)



Part II

This is almost the same tab:

G|————9—————10—————7——————8—————————————
D|——————————————————————————————————————
A|—7—————8——————9—————10————————————————
E|——————————————————————————————————————



Part III

Now play it on E and G string:

G|————9—————10—————7——————8—————————————
D|——————————————————————————————————————
A|——————————————————————————————————————
E|—7—————8——————9—————10————————————————



That's all.
One more thing: remember to play using all your fingers!!!
Enjoy :)
