I realise I have a hard time jamming / writing shred licks at tempos around 140-150 bpm. At these tempos the most natural subdivision for fast picked runs is quintuplets (5 notes per beat @144bpm = 4 notes per beat at 180bpm).
The only thing I have under my fingers is the “circular 10s” pattern (see e.g. Petrucci’s Erotomania solo among others):
-----------4-5-7-5-4-
-7-5-4-5-7-----------
which, if you think about it, is the kind of thing that just comes out by itself if you wiggle your fingers on any 3nps scale shape
Do people know any other cool quintuplet patterns (bonus points if they are not impossible on the guitar)?
