Fingerwigglin' describes a musical phenomenon wherein an alleged musician
wiggles his or her fingers
and presumes to convince the listener that the sound produced thereby is music
. In Jazz
, a player who knows a few scales (especially the Pentatonic Blues scale) but has little to no chord
knowledge and can't arpeggiate for crap often fills entire sets of tunes with mind-numbing fingerwigglin'.
Man, that pianist tonight was on fire! Too bad most of what he was doin' was obliterated by that fingerwigglin' trumpet monkey.
