{{Thumb|A Tempophon similar to the one used at the Workshop}}

The [[Tempophon]] is “a device with rotating heads that could change the pitch of a sound without modifying its tempo.”<ref>Ray White in [http://whitefiles.org/rws/r04.htm The Workshop in 1976].</ref>

<BLOCKQUOTE>
Also known as the 'Springer machine', it was released in Germany in 1955 and was a tape machine add-on allowing independent time and pitch changes on analog tape via a rotating head block and electro-mechanical sound granulation.<ref>[http://www.doornbusch.net/chronology/ ''A Chronology / History of Electronic and Computer Music and Related Events 1900-2014'']</ref><ref>[http://www.electro-sound.com/chronologie-de-la-musique-electronique/ Chronologie de la musique electronique]</ref>

The drum at the centre contains the rotating heads.
