Stevie Wonder has already proved (multiple times) what a funky beast the harpejji can be, but if you’re looking for further evidence, Vulfmon - AKA Vulfpeck’s Jack Stratton - just provided it.
His latest single, Harpejji I, is a 90-second ode to this unique electronic stringed instrument, which has been described as a cross between a piano and a guitar. It was developed in 2007 by US audio engineer Tim Meeks (AKA Marcodi Musical Products), who created a playing surface that involves whole tones ascending as you move across strings and semitones ascending as you move up them.
