Finger Combinations Pt1 – The basic idea   

     This exercise is one of those exercises everybody knows but nobody practices…for sure, it is one of the most useful, you'll see. It consist in playing up to the 12th fret and back all the possible combinations of fingers of the left hand (one at time, of course).

 These are the combinations of 2, 3 and 4 fingers.

12 13 14
21 23 24
31 32 34
41 42 43

123 124 132 134 142 143
213 214 231 234 241 243
312 314 321 324 341 342
412 413 421 423 431 432

1234 1243 1324 1342 1423 1432
2134 2143 2314 2341 2413 2431
3124 3142 3214 3241 2413 2431
4123 4132 4213 4231 4312 4321

Start maybe the 1st week with just the combinations of 2 fingers, then move to the other combinations in the following weeks, remember it is about accuracy, not how quickly you can go through the whole thing.
