Example - This doesn't work:
|----------------------------------------
|----------------------------------------
|----------------------------------------
|-------------------------------------9-
|-------------9-10-12-10-9-10-12------
|-8-10-12------------------------------
This does:
|-------------------------------------------
|-------------------------------------------
|-------------------------------------------
|---------------------9-------------------9
|-----------9-10-12------12-10-9-10-12---
|-8-10-12----------------------------------
...........................................| here is the end of the pattern (3 groups of triplet 32nds or 16ths whatever)
Emphasize the beginning of each group or cluster of notes and actually arranging your riffs in groups (triplets, 4 16th, ... groups of 5 etc) so you CAN emphasize the beginning of each one will allow you to play so much faster, right?
