let's say that we are going to design a lick that uses two hand tapping

First, we have do decide how many fingers to use on the left hand

There are 4 possible choices

after we have chosen the the left hand, then we have to choose how many fingers we will use on the right hand

There are 4 possible choices

therefore, there are 16 different combinations of left and right hand tapping methods

whenever I'm practicing, or creating new licks,

I like to use the "Tapping Sequence Diagram" to help in the creative process.

during the exercise, I like to use many of the different drills that have been previously described

When I am playing guitar with a pick, I like to use the remaining fingers on my right hand for tapping

It is a good idea to learn to utilize bending and sliding with the tapping hand

I like to use a different sequence each time, so I mark down the last one that I used

the diagram is divided into two halves, left and right, to indicate the number of fingers to use for each hand

I took the trouble to list the combinations here for you

1 finger      1 finger  
1 finger      2 fingers 
1 finger      3 fingers 
1 finger      4 fingers 
2 fingers     1 finger  
2 fingers     2 fingers 
2 fingers     3 fingers 
2 fingers     4 fingers 
3 fingers     1 finger  
3 fingers     2 fingers 
3 fingers     3 fingers 
3 fingers     4 fingers 
4 fingers     1 finger  
4 fingers     2 fingers 
4 fingers     3 fingers 
4 fingers     4 fingers
