A simple groove in tapping technique.
Both hands play the arpeggio so the speed can be higher.
play D and A win fingers L1 and L3,then F with R1 and R3,then A L3,A# R2,G L1 and A R2.
The pattern is entirely in 16th,so start with a low metronome tempo (i think 60bpm it's the best) and then slowly speed up.
enjoy!
