There are 3 Blues patterns in bass playing. They each consist 
of three different root notes. 

*Pattern 1 
The 1st root is on the E string 5th fret. The 2nd root is on the A 
string 5th fret. And the 3rd root is on the A string 7th fret. 

*Pattern 2 
The 1st root is on the A string 7th fret. The 2nd root is on the E 
string 7th fret. And the 3rd root is on the E string 5th fret. 

*Pattern 3 (Only Used When The Pattern Uses ALL FOUR STRINGS) 
All roots start on the E string. The 1st root is the 2nd fret. The 
2nd root is the 8th fret. And the 3rd root is the 10th fret. 

To play a 12 bar blues... You find a certain pattern in a 4/4 beat. 
You start the pattern on the first root and play 4 measures. Then 
you go to the 2nd root and play 2 measures before returning back 
to the 1st to play 2 measures. Then you play 1 measure each on the 
3rd root, 2nd root, 1st root, and then to finish 1 measure on the 
3rd root.

No matter what pattern you use, the order of the root notes never 
change. The root order is always— 1,1,1,1,2,2,1,1,3,2,1,3. 
I used a really simple pattern for each example (they probably 
sound like crap) You can always throw your own pattern in there. 
Also, try to throw in some eight and sixten notes. Triplets always 
sound nice to.
