During this version of Letting Go, Tim plays a little intro before he starts the song. Is there a phrase for how Tim is playing at 14 seconds. He uses his strumming hand and runs his fingers like a motor boat. Is that a Tim original or is that a legitimate technique?
that's not a classical guitar technique that i know of; he seems to be hitting the strings with the front of his fingernails with a downstroke motion. that's more of a flamenco thing.
