What it is

Hammond devised an electromechanical organ that generates sound with metal tonewheels spinning next to electromagnetic pickups, combining harmonics via sliding drawbars, a far more compact and affordable alternative to the giant Telharmonium. The Model A, launched in 1935, became an iconic instrument of jazz, gospel and rock.

What it led to

  • Organ music in jazz and gospel
  • Later electronic synthesizers
