Been workin on my fiddle-stlye chops. Zack kinda introduced me to the technique on fiddle last year. Then Ira came to a soapbox string session and amazed me with his cello chopping skills, and re-affirmed my faith that it could be done on an instrument with semi-vertical as opposed to horizontal strings. Here’s a couple violinists (Darol Anger, some other dude and then Casey Driessen killin it) doing the chop on youtube.
