Source: Wikipedia. We are a little late on this one, but there has not been much talk of Cor Fuhler’s passing.
Cornelis William Hendrik Fuhler (3 July 1964 – 19 July 2020) was a Dutch/Australian improvisor, composer, and instrument builder associated with free jazz, experimental music and acoustic ecology. He played piano by manipulating sound with electromagnetic string stimulators like Ebows and motorized actuators. Fuhler also performed on guitar, turntables and synthesizer. He invented the keyolin, a combination of keyboard and violin.
