The ‘Electrone’ and ‘Melotone’ Leslie Bourn, United Kingdom, 1932


Since the 1920’s the Compton Organ Co had been the premier manufacturer of pipe organs for cinemas, churches and dance halls in the UK. In 1932 Compton developed their first electronic “pipe-less” organ the ‘Melotone’ intended as an add-on unit for conventional organs to extend their range. The Melotone’s sound was generated using the same tone-wheel technique as the Hammond Organ and the much earlier Telharmonium (1876), where a metal disc engraved with representations of sound waves spun within a magnetic field generating varying voltage tones. In this case two electrostatic tone wheels provided the sounds, amplified and fed to a large speaker horn in the organ loft. The Melotone was not intended as a complete instrument in itself and had it’s own ethereal synthetic character to contrast with a traditional pipe organ.

In 1938 Compton developed the Melotone concept into a stand-alone organ called the Electrone (or Theatrone) designed as a replacement for old pipe organs in churches and dance halls. This instrument had twelve tone generators and an organ-stop style range of voices. A post-war compact ‘economical’ version was brought out in 1952 also called the ‘Melotone’. Production of the organs continued until the 1960’s by which time tone-generator technology had become obsolete due to the arrival of cheaper and more dependable solid-state electronic circuitry.

    1. How can I share pics of Leslie Bourn .
      He was my Grandfather.
      I have some photos of the organ he built at home

  1. The Melotone does not use the same electromagnetic tonewheeel system as the Hammond organ. Leslie Bourn, for Compton, developed a system of stationary multi-tracked discs scanned by a rotating pick-up disc in an electrostatic field, thus generating an small induced alternating voltage which was amplified. Bourn had started developing a magnetic tonewheel system in the late 1920s, but he switched to the investigation of electrostatics after a couple of years or so.

  2. My Grandfather was Leslie Bourn.
    I would love to share a few photos of the electrone organ he built at home

  3. David – I would be delighted to get in touch and find out more from you about your grandfather and his work. I have been researching the Electrone and other Compton innovations for some years and have built up a nearly comprehensive collection of 21 different models from 1938 to 1970.
