I'm looking for the name of a Technique where Strings will be picked very fast in an arpeggio so sounds like a strumm.

Unfortunately this is the only example i found for this, you can see him doing it at 0:26 https://www.youtube.com/watch?v=VHbPKAvgUH0

but ive seen it pretty often already, maybe you know a better one.

have a nice day guys!
