Scope note:

A brand and type of electronic musical keyboard instrument developed by Harry Chamberlin in conjunction with a London-based manufacturer, which incorporated a selection of electromagnetic tape samples, as looped recordings played by pressing the keys of a keyboard. The prototype, the Mellotron Mark II, was available in 1964, and was used by numerous pop and rock groups, such as the Beatles and the Moody Blues.
