  (1949–)
  Following World War II, most electronic home organs were built in a configuration usually called a spinet organ, which first appeared in 1949. These compact and relatively inexpensive instruments became the natural successors to reed organs. They were marketed as competitors of home pianos and often aimed at would-be home organists who were already pianists (hence the name "spinet", in the sense of a small upright piano). The instrument's design reflected this concept: the spinet organ physically resembled a piano, and it presented simplified controls and functions that were both less expensive to produce and less intimidating to learn. One feature of the spinet is automatic chord generation; with many models, the organist can produce an entire chord to accompany the melody merely by playing the tonic note, i.e., a single key, on a special section of the manual.
