This guy can play the chromatic harp. Did I mention that he can play? Can he ever. I can’t tell for sure what instrument he’s using, but it might be a CBH 2016, which is certainly the very thing for playing as fast as this guy plays. The mic appears to be an Audix Fireball with a wireless setup.
Speed is not a problem for Mr. Fagundes, and he can obviously handle scales and arpeggios at tempos that most harp players have problems counting, let alone playing. He’s got plenty of videos on Youtube; check him out and schedule some more practice time for yourself.
