Well, I'll start off with what I can call myself proficient at; Guitar, bass guitar, tenor guitar (tuned in fifths), mandolin and mandolin family/bozouki, tenor banjo. Others that I can make some reasonable attempt at following a tune; Harmonica (chromatic, not a blues/slide harp), piano (sort of), organ/synth (slightly better), five string banjo (okay but not good enough to make a living at it), Highland bagpipes (my neighbors hate me). What do you play?
