The story
William "O'Neil" Spencer was a jazz drummer and singer. He is most known for his work in the John Kirby Sextet. According to a Jazz Profiles Blogspot on 8 August 2008 and an interview with legendary jazz drummer Philly Jo Jones, "O'Neil" is credited with the invention of the hi-hat in 1942. Prior to 1942, drummers used a "low-hat". A similar configuration with closing cymbals and foot pedal, but only extending about 12 inches off the ground. The higher position of the cymbals allows a drummer to hit the cymbals in an open or closed position for additional sounds during play. The hi-hat has become standard drumset equipment.
