Try to play the normal minor or harmonic minor scale sequenced in 4s on a single string, but instead of playing it in a 16ths groove play it in triplets/sextuplets style groove. So much more pleasing to hear it this way, but much harder to break your habit of a 16ths groove. Good luck!
Bonus challenge
Instead of starting on the root note of the sequence offset it with a different note. And by this I mean to start on a different finger than the index or pinky.
No cheating!
You can use a pencil to write it on paper, but dont use a program to sequence it to listen to it! Figure it out for yourself!
