This scale run kicks my arse! Basically, the B Locrian 3 Notes Per String scale/mode shape is what I'm using.
The 16th notes use a 3 note pattern because you end up hitting the same note twice in one beat. If you number the notes in each beat as 1, 2, 3, then the pattern would go 1, 3, 2, 1.
After completing that pattern for the first beat, you go one note lower in key and repeat the 1, 3, 2, 1 descending pattern. This happens for 3 beats.
On the fourth beat, a sextuplet (aka: 16th note triplet) ascending run occurs.
Because you're bouncing all over the place, plus a very fast sextuplet burst, this particular scale run is VERY difficult for me to get going blazingly fast.
HEY!!! Does Your Rhythm SUCK!?
